On Current-Voltage And Capacitance-Voltage Characteristics Of Metal-Semiconductor Contacts, Abdulmeci̇t Turut
On Current-Voltage And Capacitance-Voltage Characteristics Of Metal-Semiconductor Contacts, Abdulmeci̇t Turut
Turkish Journal of Physics
It is expected the fact that the current following across metal-semiconductor (MS) rectifying contact named as Schottky barrier diode(SBDs)and effect of sample temperature on their electrical properties obey thermionic emission (TE) current model. But, it has been seen that the abnormal behaviors in the measured electrical characteristics cannot be exactly under stood by the classical TE transport theory. Intheliterature, the observed abnormal behaviors have been successfully explained by a Gaussian distribution function and by the pinch-off model being interaction of the neighbor patches suggested by Tung and coworkers, the named discrete regions model as "patches" with low barrier placed in …

Quantum Gravity Correction To The Thermodynamic Quantities Of The Charged Drgt Black Hole, Gani̇m Geçi̇m
Turkish Journal of Physics
In this study, in the framework of the Hamilton approach, the quantum gravity effect on Hawking temperature, on the specific heat capacity, and on the stability conditions of the charged de Rham, Gabadadze, and Tolley (dRGT) black hole are investigated by using the tunneling processes of both charged massive scalar and Dirac particles. It is shown that quantum corrected Hawking temperature depends not only on the black hole properties but also on the properties of the tunnelling particles. It is also observed that quantum corrected Hawking temperature is lower than that of the standard Hawking temperature. Also, the specific heat …

Scintillation Timing Characteristics Of Common Plastics For Radiation Detection Excited With 120 Gev Protons, James Wetzel, Emrah Tiraş, Burak Bi̇lki̇, Ni̇lay Bostan, Ohannes Kamer Köseyan
Turkish Journal of Physics
The timing characteristics of scintillators must be understood in order to determine which applications they are appropriate for. Polyethylene naphthalate (PEN) and polyethylene teraphthalate (PET) are common plastics with uncommon scintillation properties. Here, we report the timing characteristics of PEN and PET, determined by exciting them with 120GeVprotons. The test beam was provided by Fermi National Accelerator Laboratory, andthescintillators were tested at the Fermilab Test Beam Facility. PEN and PET are found to have dominant decay constants of 34.91 ns and 6.78 ns, respectively.
The Calculation Of Total Fragment Excitation Energy For Photofission Of Uranium Isotopes, Mojtaba Jamiati, Payam Mehdipour Kaldiani
The Calculation Of Total Fragment Excitation Energy For Photofission Of Uranium Isotopes, Mojtaba Jamiati, Payam Mehdipour Kaldiani
Turkish Journal of Physics
The total excitation energy as a function of fragment mass (TXE/A) are calculated for neutron induced fission of $^{235}$U and photofission of $^{238}$U by using the statistical model. With comparing the calculated results and the experimental data, the statistical model is modified. In new modified model, TXE are calculated by adding the neutron binding energy to the deformation energy. The calculated results using modified statistical model are in good agreement with the experimental data. Then, the total excitation energy as a function of fragment mass (TXE/A) are evaluated for photofission of Uranium isotopes.

Gup Effects On Hawking Temperature In Riemann Space-Time, Yumnam Kenedy Meitei, Telem Ibungochouba Singh, Irom Ablu Meitei
Turkish Journal of Physics
In this paper, the modified Hawking temperature of a static Riemann space-time is studied using the generalized Klein-Gordon equation and the generalized Dirac equation. Applying the Kerner-Mann quantum tunneling method, the modified Hawking temperatures for scalar particles and fermions that cross the event horizon of the black hole have been derived. We observe that the quantum gravity effects reduce the rise of thermal radiation temperature of the black hole.
Network Dynamics Reconstruction From Data, Deni̇z Eroğlu
Network Dynamics Reconstruction From Data, Deni̇z Eroğlu
Turkish Journal of Physics
We consider the problem of recovering the model of a complex network of interacting dynamical units from time series of observations. We focus on typical networks which exhibit heterogeneous degrees, i.e. where the number of connections varies widely across the network, and the coupling strength for a single interaction is small. In these networks, the behavior of each unit varies according to their connectivity. Under these mild assumptions, our method provides an effective network reconstruction of the network dynamics. The method is robust to a certain size of noise and only requires relatively short time series on the state variable …

Investigating Above-Bandgap And Below-Bandgap Optical Transition In Gabias Epilayers By Photoreflectance Spectroscopy, Ömer Dönmez, Ayşe Erol
Turkish Journal of Physics
We present optical identification of deep level defects in as-grown and annealed GaBixAs$_{1-x}$ (x $=$ 0, 0.013 and 0.015) alloys grown at different temperatures (220 \textdegree C and 320 \textdegree C) by using photo-modulated reflectance (PR) spectroscopy and photoluminescence (PL). The PR measurements are employed at above- and below-bandgap excitations, and the PR line-shape is analyzed by the third derivative functional form (TDFF). The PR at below-bandgap excitation reveals transitions at 0.757 \textpm 0.001 eV and 0.710 \textpm 0.002 eV at 30K and 300K, respectively. Franz-Keldysh oscillations are observed in all samples under above-bandgap excitation at PR measurements, and the …
Weak Deflection Angle Of Black-Bounce Traversable Wormholes Using Gauss-Bonnet Theorem In The Dark Matter Medium, Ali Övgün
Turkish Journal of Physics
Inthispaper, wefirstusetheopticalmetricsofblack-bouncetraversablewormholestocalculatetheGaussian curvature. Then we use the Gauss-Bonnet theorem to obtain the weak deflection angle of light from the black-bounce traversable wormholes. We investigate the effect of dark matter medium on weak deflection angle using the Gauss-Bonnet theorem. We show how weak deflection angle of wormhole is affected by the bounce parameter a. Using the Gauss-Bonnet theorem for calculating weak deflection angle shows us that light bending can be thought as a global and topological effect.

Unraveling Energy Consumption By Using Low-Cost And Reevaluated Thermoelectric Thin Films, Gi̇zem Durak Yüzüak, Seray Özkan, Ercüment Yüzüak
Turkish Journal of Physics
Energy is undoubtedly one of our most important demands whose consumption is constantly increasing and will continue to increase soon. One of the most important factors in attaining the required energy is to provide high efficiency at a low cost with the help of new technological improvements by evaluating wastes. Energy demand could be achieved for a relatively large thermoelectric power value by recycling the Peltier modules from waste ones and adjusting their properties with nanotechnology. For this aim, thermoelectric thin film modules were grown on silicon (Si), glass, and Kapton substrates with thermal evaporation method by using two different …

Quantum Thermodynamics And Quantum Coherence Engines, Asli Tuncer Özdemi̇r, Özgür Esat Müstecaplioğlu
Turkish Journal of Physics
The advantages of quantum effects in several technologies, such as computation and communication, have already been well appreciated. Some devices,such as quantum computers and communication links,exhibiting superiority to their classical counterparts,have been demonstrated. The close relationship between information and energy motivates us to explore if similar quantum benefits can be found in energy technologies. Investigation of performance limits for a broader class of information-energy machines is the subject of the rapidly emerging field of quantum thermodynamics. Extension of classical thermodynamical laws to the quantum realm is far from trivial. This short review presents some of the recent efforts in this …

Transfer Matrix In Scattering Theory: A Survey Of Basic Properties And Recent Developments, Ali̇ Mostafazadeh
Turkish Journal of Physics
We give a pedagogical introduction to time-independent scattering theory in one dimension focusing on the basic properties and recent applications of transfer matrices. In particular, we begin surveying some basic notions of potential scattering such as transfer matrix and its analyticity, multidelta-function and locally periodic potentials, Jost solutions, spectral singularities and their time-reversal, and unidirectional reflectionlessness and invisibility. We then offer a simple derivation of the Lippmann-Schwinger equation and the Born series, and discuss the Born approximation. Next, we outline a recently developed dynamical formulation of time-independent scattering theory in one dimension. This formulation relates the transfer matrix and therefore …
Optimization Of Collection Optics For Maximum Fidelity In Entangled Photon Sources, Kadi̇r Durak
Optimization Of Collection Optics For Maximum Fidelity In Entangled Photon Sources, Kadi̇r Durak
Turkish Journal of Physics
In this report,decoherence sources for entangled photons created by spontaneous parametricdown-conversion phenomenon are studied. The phase and spatial distinguishability of photon pairs from orthogonal crystals reduce the maximum achievable entanglement fidelity. Carefully chosen compensation crystals are used to erase the phase and spatial traces of down-conversion origins. Emission angle of photon pairs also leads to optical path difference and results in phase distinguishability. A realistic scenario is numerically modelled, where the photon pairs with nonzero emission angle gather a phase difference. These pairs can still be collected and manipulated for practical use but the collection optics adds upon the phase …

Tuning The Magnetic Field Sensitivity Of Planar Hall Effect Sensors By Using A Cr Spacer Layer In A Nife/Cr/Irmn Trilayer Structure, Hasan Pi̇şki̇n, Numan Akdoğan
Turkish Journal of Physics
Planar Hall effect (PHE)-based magnetic field sensors have recently received considerable attention due to their fascinating properties. For the NiFe/spacer/IrMn trilayer PHE sensor structures, tuning the exchange bias via a spacer layer is very crucial due to its direct effects on the sensor's magnetic field sensitivity. Here the effect of Cr spacer layer thickness on PHE sensitivity and exchange bias is investigated in NiFe (10 nm)/Cr (t$_{Cr})$/IrMn (20 nm) trilayer structures where the t$_{Cr}$ varied between 0.0 nm and 1 nm with a step of 0.1 nm. As the t$_{Cr}$ increased, we observed a fast decrease in exchange bias field. …

Analysis Of Chaotic And Regular Behavior Of Matinyan-Yang-Mills-Higgshamiltonian System, Engi̇n Kandiran, Avadi̇s Si̇mon Hacinliyan
Turkish Journal of Physics
In this study we analyze the Matinyan-Yang-Mills-Higgs (MYMH) system, based on semiclassical solutions to a Yang-Mills model, using Poincaré surfaces of section and the method of averaging. To investigate the possible chaotic behavior for the system, we simulate the trajectories of the system and calculate the Lyapunov exponents. We observe that the system displays weakly chaotic behavior. We search for the existence of approximately conserved quantities for the system using the method of averaging. In this way, we show the existence of four fixed points where period orbits exist.

Octonion Form Of Duality-Invariant Field Equations For Dyons, Mustafa Emre Kansu, Murat Tanişli, Süleyman Demi̇r
Turkish Journal of Physics
The hypothetical particles dyons, which carry both electric and magnetic charges simultaneously, are widely discussed in application to electromagnetic theory and magnetohydrodynamics. Particularly, the duality-invariant field equations were suggested with suitable definitions of the dyon's electromagnetic characteristics. In this study, we propose an alternative formulation of the duality-invariant field equations for dyons based on octonion algebra. Octonions have been used to express the equations for potentials, field strengths, and sources in a more compact and consistent manner. Additionally, the octonionic form of the energy conservation law for dyons has been derived.
The Effect Of Temperature On Fusion Cross-Sections Of The 8b Proton Halo Nucleus, Murat Aygün
The Effect Of Temperature On Fusion Cross-Sections Of The 8b Proton Halo Nucleus, Murat Aygün
Turkish Journal of Physics
In the present study, I investigate the effect of temperature on fusion cross-sections of the 8B proton halo projectile. For this purpose, I evaluate two different fusion reactions, 8B + 28Si and 8B +58Ni, in the available literature. I apply two different nuclear potentials as a function of temperature. I calculate both fusion cross-sections and nuclear potentials for both reactions and I then compare the theoretical results with the experimental data. This comparison provides an opportunity for a test of different temperature-dependent potentials in explaining the fusion cross-sections with the 8B halo nucleus.

Cladding light strippers are essential components in high-power fiber lasers used for removal of unwanted cladding light that can distort the beam quality or even damage the whole fiber laser system. In this study, an Atomic Layer Deposition system was used for the first time to prepare the cladding light stripper devices using a 40 nm thick zirconia layer grown on optical fiber. The thickness of the zirconia coating was confirmed using the Scanning Electron Microscopy (SEM) and the Ellipsometry techniques. The elemental analysis was also performed using the wavelength dispersive X-ray spectroscopy technique. The Raman spectroscopy and XRD data …

Turkish Journal of Physics
In the present work, ZnO films were obtained on mesoporous silicon substrates by the method of HF magnetron sputtering of a metallic zinc target in reaction oxygen and argon gas medium. The properties of the ZnO films obtained on mesoporous substrates were studied depending on the ratio of the partial pressures of the working gases (argon/oxygen). X-ray analysis showed that in the process of deposition, the ZnO films of a hexagonal structure were formed. The effect of the porous layer on the structural and luminescent properties of the thin ZnO films was studied. The results showed that the porous silicon …

Anisotropic Magnetoresistance And Planar Hall Effect In Magnetoresistivenife/Pt Thin Film, Erdem Demi̇rci̇
Turkish Journal of Physics
The magnetoresistive NiFe/Pt sensor was fabricated by using standard microlithography and sputter deposition techniques and then the magnetic and magnetotransport properties were investigated. The magnetic properties of the sample show that the easy axis of magnetization prefers a predefined direction along the Hall bar. Moreover, the sample has uniaxial magnetic anisotropy due to the growth-induced magnetic anisotropy. On the other hand, the Anisotropic magnetoresistance (AMR) and the Planar Hall effect (PHE) of the sample were investigated in detail between 0° and 360°. The angle-dependent AMR and PHE signals at the in-plane magnetic field of constant magnitude intersect at certain angles. …

Frequency And Voltage Dependence Of Electrical Conductivity, Complex Electricmodulus, And Dielectric Properties Of Al/Alq3 /P-Si Structure, İkram Orak, Abdulkeri̇m Karabulut
Turkish Journal of Physics
In order to enhance the capacitance of the Al/p-Si metal-semiconductor structure, the Alq3 thin film was coated between these two layers using the spin coating technique as the interlayer. The electrical conductivity, real and imaginary parts of electric modulus, dielectric loss and dielectric constant parameters were examined at the room temperature by the help of admittance measurements in the 100 kHz to 1 MHz frequency range. The effect of frequency on the dielectric constant and dielectric loss values is negligible at the negative voltage values, up to about 0.8 V, and these values rapidly ascended after 0.8 V. The function …

Four-Quark Exotic Mesons, Shahin Agaev, Kazem Azizi, Hayri̇ye Sundu Pamuk
Turkish Journal of Physics
We review our investigations devoted to the analysis of the resonances Zc(3900), Zc(4430), Zc(4100), X(4140), X(4274), α1(1420), Y(4660), X(2100), X(2239), and Y(2175) discovered in various processes by Belle, BaBar, BESIII, D0, CDF, CMS, LHCb and COMPASS collaborations. These resonances are considered as serious candidates to four-quark (tetraquark) exotic mesons. We treat all of them as diquark-antidiquark states with relevant spin-parities, find their masses and couplings, as well as explore their dominant strong decay channels. Calculations are performed in the context of the QCD sum rule method. Thus, the spectroscopic parameters of the tetraquarks are evaluated using the two-point sum rules. …

Size-Dependent Electron Chemical Potential In Nanostructures Derived Fromstatistical Configuration, Desyana Olenka Margaretta, Nadya Amalia, Fisca Dian Utami, Riri Murniati, Sparisoma Viridi, Mikrajuddin Abdullah
Turkish Journal of Physics
We rederived the fermion distribution function by considering the effect of assembly size. We did not use Stirling approximation to avoid the deviation generated by this approximation for a small number of constituents and small assembly size. Furthermore, we identified that in small systems, the chemical potential should also depend on the assembly size. We also rederived a general expression for the size-dependent chemical potential from a statistical configuration and showed that it is consistent with the results from previously reported theoretical or simulation methods. Finally, we applied the model to derive a size-dependent thermoelectric power factor of nanostructured materials. …

Prediction Of Standard Enthalpies Of Formation Of Boron Nitride Nanocones, Fahimeh Shojaie
Turkish Journal of Physics
Prediction of the standard enthalpy of formation (ΔfH0298) of boron nitride nanocone (BNNCs) structures with disclination angles 60°, 120°, and 180°is recommended to be performed by the isodesmic reaction approach. NH3, BH3, and N2H4 were selected as key reference compounds. In order to calculate ΔfH0298 of nanocones, we must first calculate the enthalpies of nanocone rings at their apexes. For this purpose, ΔfH0298 values of 40 different structures, such as boron, nitrogen, and hydrogen compounds, have been calculated by combining Gaussian-4 (G4) theory calculations with the isodesmic and other balanced reactions approach. At each stage of the calculations, the previously …

Electrophysical Properties Of Pb 1-Xmnx Se Epitaxial Films Irradiatedby Γ-Quanta, Rahim Madatov, Rakshana Mamishova, Muslim Mamedov, Javanshir Ismayilov, Ulviya Faradjova
Turkish Journal of Physics
Herein, the effect of γ-quanta on electrophysical and photoelectric properties of p-type Pb1-xMnx Se epitaxial films obtained from the molecular cluster on the glass substrate by the method of condensation has been investigated. It has been established that the acceptor-type local levels with the ionization energy of 0.14 eV and 0.175 eV are generated, when p-type Pb1-xMnx Se (x = 0.01) epitaxial films are irradiated by γ-quanta at D >10 kGy doses. The increase in the photoconductivity in the low temperature range 80-180K is due to the discharge of 0.14eV level, but the decrease in the rate of change of …

On-Chip Quantum Optics And Integrated Optomechanics, David Hoch, Timo Sommer, Sebastian Mueller, Menno Poot
Turkish Journal of Physics
Recent developments in quantum computing and the growing interest in optomechanics and quantum optics need platforms that enable rapid prototyping and scalability. This can be fulfilled by on-chip integration, as we present here. The different nanofabrication steps are explained, and our automated measurement setup is discussed. We present an opto-electromechanical device, the H-resonator, which enables optomechanical experiments such as electrostatic springs and nonlinearities and thermomechanical squeezing. Moreover, it also functions as an optomechanical phase shifter, an essential element for our integrated quantum optics efforts. Besides this, the equivalent of a beam splitter in photonics-the directional coupler-is shown. Its coupling ratio …
Local Vibrational Modes Of Natural Isotopes Of Substitutional Oxygen In Cdte, Enver Tarhan, Anant K. Ramdas
Local Vibrational Modes Of Natural Isotopes Of Substitutional Oxygen In Cdte, Enver Tarhan, Anant K. Ramdas
Turkish Journal of Physics
We investigated the localized vibrational modes (LVM) of natural oxygen containing $^{16}$O, $^{17}$O, and $^{18}$O isotopes at a substitutional tellurium site in cadmium telluride using infrared absorption spectroscopy at cryogenic temperatures. The main absorption peak observed at 350 cm$^{-1\, }$was formerly attributed to a fundamental LVM mode ($\nu _{0})$ of oxygen at a tellurium site. The relatively weak absorption peaks observed at 331 cm$^{-1\, }$and 340 cm$^{-1\, }$are assigned as the same $\nu_{0}$ mode of the $^{17}$O and $^{18}$O isotopes, respectively, based on their relative intensities and spectral positions. The spectral positions were confirmed with theoretical calculations using a linear …

Turkish Journal of Physics
The present work mainly purposed to investigate significant nuclear structure properties nuclei used in single photon emission computed tomography (SPECT), in addition to ground state nuclear properties such as the binding energy per particle, the root mean square (rms) charge, and proton and neutron radii. Besides, we calculated the neutron skin thicknesses (NST), the proton, neutron quadrupole moments ($Q_{P}, Q_{N})$, quadrupole deformation parameter ($\beta_{2})$, and the proton and neutron pairing energies ($P_{P}, P_{N})$ to determine shapes and deformations of SPECT nuclei including odd-odd or odd-even/even-odd nuclei in axial symmetry for Skyrme and Gogny interactions. To analyze the accuracy of the …

A Nonminimally Coupled, Conformally Extended Einstein-Maxwell Theory Of Pp-Waves, Dündar Teki̇n Dereli̇, Yorgo Şeni̇koğlu
Turkish Journal of Physics
A nonminimal coupling of Weyl curvatures to electromagnetic fields is considered in Brans-Dicke-Maxwell theory. The gravitational field equations are formulated in a Riemannian spacetime where the spacetime torsion is constrained to zero by the method of Lagrange multipliers in the language of exterior differential forms. The significance and ramifications of nonminimal couplings to gravity are examined in a pp-wave spacetime.
Pseudoscalar Form Factors Of The $\Delta(1232)$ In Baryon Chiral Perturbation Theory, Yasemi̇n Ünal
Pseudoscalar Form Factors Of The $\Delta(1232)$ In Baryon Chiral Perturbation Theory, Yasemi̇n Ünal
Turkish Journal of Physics
The pseudoscalar current-delta transition form factors are calculated in the framework of relativistic baryon chiral perturbation theory including order $\mathcal{O}(q^4)$. The complex-mass scheme, which is suitable and well-defined for unstable particles, is taken into account as a renormalization scheme. We discuss the low energy behavior of the pseudoscalar $\tilde{g}(Q^2)$ and $\tilde{h}(Q^2)$ form factors and note that the momentum dependence of the form factors is dominated by the pion pole contributions.

Theoretical Description Of The Two-Color Photoelectron Spectra Process Of Hydrogen: Comparison Between Tdse Calculation And Kroll And Watson Approach, Souhaila Chaddou, Soumia Chqondi, Abdelmalek Taoutioui, Abdelkader Makhoute
Turkish Journal of Physics
We present a theoretical study of the main characteristics of two-color photoionization of hydrogen atoms by short strong laser pulses. Our numerical approach is performed by numerically solving the time-dependent Schrödinger equation for a hydrogen atom interacting with Ti:sapphire laser radiation combined with its 15th harmonic. The energy spectra obtained by the direct numerical solution of the Schrödinger equation are compared with those given by the Kroll and Watson perturbative approach. This comparison allows us to check the reliability of the latter approximation.
