The static elastic constants (C_{11}, C_{12} and C_{44}), pressure derivative of elastic constants, pressure derivative of bulk modulus, propagation velocities of longitudinal and transverse waves in [100], [110] and [111] directions and Young modulus are investigated through computations using the higher-order perturbation theory based on pseudopotential formalism, in which we have applied our own proposed model potential for GaP, GaAs and GaSb semiconductor compounds. In the present calculations, two local-field correction functions are employed to consider exchange and correlation effects. The numerical values of the aforesaid properties are found to be sensitive to the selection of the local-field correction function …
Determination Of Barrier Height Temperature Coefficient By Norde's Method In Ideal Co/N-Gaas Schottky Contacts, Abdulmeci̇t Turut
Determination Of Barrier Height Temperature Coefficient By Norde's Method In Ideal Co/N-Gaas Schottky Contacts, Abdulmeci̇t Turut
Turkish Journal of Physics
We have formed the ideal Co/n-GaAs Schottky barrier diodes (SBDs) by magnetron DC sputtering. The experimental current-voltage data of the Co/n-GaAs SBD are almost independent of the sample temperature and quite well obey the thermionic emission model from 100 K to 320 K. We have showed that the temperature coefficient of the barrier height can be determined using Norde's method instead of the temperature-dependent capacitance-voltage measurements or the flat-band barrier height values because the thermionic emission current dominates in the ideal SBDs. We have obtained a barrier height temperature coefficient value of \alpha = 0.41 meV/K for Co/n-GaAs SBDs used …

Structure And Electrical Properties Of Lanthanum Doped Bi_2sr_2ca_{2-X}La_Xcu_3o_{10+ \Delta} Superconductor, Kareem Jasim
Turkish Journal of Physics
In this work we studied the effect of La-doping on phase purity, crystal structure and electrical resistivity of Bi_2Sr_2Ca_2Cu_3O_{10+\delta} superconductor, synthesized by usual solid state reaction method. The X-ray florescence (XRF) show the stoichiometry of samples and X-ray diffraction (XRD) analysis showed the change of structure from orthorhombic to tetragonal by increasing La doping. It was found that the change of lanthanum concentrations of all our samples produce a change in the oxygen content, the ratio of lattice parameters c/a and mass density \rho_m. Electrical resistivity, using the four-probe technique, was used to find the critical temperature T_c and to …

Effect Of Zinc Incorporation On The Density Of Defect States In A-Se_{85}Te_{15} Glassy Alloy, Shikha Shukla, Santosh Kumar
Turkish Journal of Physics
Present work incorporates the study of d.c. conductivity measurements at high electric fields in vacuum evaporated thin films of Se_{85-x}Te_{15}Zn_x (x = 0, 2, 4, 6 and 10) glassy alloys. Current-Voltage (I-V) characteristics have been measured at various fixed temperatures. In these samples, at low electric fields, ohmic behavior is observed. However, at high electric fields (E \sim 10^4 V/cm), non ohmic behavior is observed. An analysis of the experimental data confirms the presence of space charge limited conduction (SCLC) in the glassy materials studied in the present case. From the fitting of the data to the theory of SCLC, …

Branching Of The W(H_4) Polytopes And Their Dual Polytopes Under The Coxeter Groups W(A_4) And W(H_3) Represented By Quaternions, Mehmet Koca, Nazi̇fe Koca, Mudhahir Al-Ajmi
Turkish Journal of Physics
4-dimensional H_4 polytopes and their dual polytopes have been constructed as the orbits of the Coxeter-Weyl group W(H_4), where the group elements and the vertices of the polytopes are represented by quaternions. Projection of an arbitrary W(H_4) orbit into three dimensions is made preserving the icosahedral subgroup W(H_3) and the tetrahedral subgroup W(A_3). The latter follows a branching under the Coxeter group W(A_4). The dual polytopes of the semi-regular and quasi-regular H_4 polytopes have been constructed.

Neutron total and differential elastic scattering cross-sections for ^{55}Mn nucleus was calculated from different global spherical optical potential (SOP) sets for different neutron energies ranging from 0.2 MeV to 22 MeV using the well known computer program SCAT-2 on an IBM PC-AT. In addition, the angular distributions of elastically scattered neutrons at different neutron energies were calculated. The results were compared with those of the experimental data obtained from the EXFOR data file of NEA data bank. The best-fit potential parameter was thereby selected. It was observed that the best fit to the experimental values of the total cross-sections are …

\Delta (E2/M1) And X(E0/E2) Mixing Ratios In ^{134}Ba By Means Of Ibm-2, Abdul Ridha Hussain Subber, Flih Hussain Al-Khudair
Turkish Journal of Physics
The ^{134}Ba isotope (Z = 56) lies in the transitional region closer to the vibrational range of nuclei. Energy levels B(E2), B(M1) and the mixing ratios \delta (E2/M1) and X(E0/E2) for selected transitions were calculated in the framework of the proton-neutron interacting boson model (IBM-2). All results were compared with experimental data. Some experimental X(E0/E2) ratios were calculated from available experimental data. Majorana parameters were found to have a great effect on the calculated energy levels of the 2_3^+ and 2_4^+, which indicate that both of them have mixed symmetry properties.

Hydrogen Implantation Effects On The Electrical And Optical Properties Of Inse Thin Films, Atef Fayez Qasrawi, Khaled Faisal Ilaiwi, Antonio Polimeni
Turkish Journal of Physics
The effects of hydrogen ion implantation on the structural, electrical and optical properties of amorphous InSe thin films have been investigated. X-ray diffraction analysis revealed no change in the structure of the films. An implantation of 7.3 x 10^{18} ions/cm^2 decreased the electrical conductivity by three orders of magnitude at 300 K. Similarly, the conductivity activation energy, which was calculated in the temperature range of 300-420 K, decreased from 210 to 78 meV by H-ion implantation. The optical measurements showed that the direct allowed transitions energy band gap of amorphous InSe films has decreased from 1.50 to 0.97 eV by …
Full Polar Optical Phonon States And Dispersive Spectra Of A Wurtzite Gan/Aln Rectangular Quantum Wire, Li Zhang
Turkish Journal of Physics
Within the framework of the dielectric continuum model and Loudon's uniaxial crystal model, the full polar optical phonon modes including the quasi-confined (QC) modes, the propagating (PR) modes, the half-space (HS) modes, and the interface optical (IO) modes in a quasi-one-dimensional (Q1D) wurtzite rectangular quantum wire (QWR) structure are deduced and analyzed. The analytical phonon states, their dispersion equations and polar polarization eigenvectors are derived. Numerical calculation of dispersive spectra for these modes is performed on a wurtzite GaN/AlN rectangular QWR. The behavior of the QC mode reducing to the IO mode is observed clearly in the dispersive curves of …

Near-Resonant Diurnal Reactions: A Physical Model Applicable To Origin Of Life Processes, Eddwin Budding, Cüneyt Aki, Osman Demi̇rcan, Bülent Gündüz, Güngör Gündüz, Mehmet Emi̇n Özel
Turkish Journal of Physics
We adopt that the large residual chemical potential energy (CPE) among reagents of the biosphere constitutes the key physical problem posed by life. We associate the formation of this CPE with the near-resonant behaviour of a two-stage `A-B' molecular process that behaves as a self-sustaining parametric oscillator. Under suitable conditions, such an oscillator generates CPE when forced by a periodic (daily) insolation. The net growth factor required to explain the current mean excess of biospheric CPE is \sim 5 x 10^{-12} d^{-1}. This aligns with the mean exponential coefficient of secular oxygen generation in the terrestrial atmosphere. It is also …

Nuclear Structure Of Xe-Pt Nuclei In The Framework Of Arm And Odd-Even Staggering, Harish Mohan Mittal, Vidya Devi
Turkish Journal of Physics
The asymmetric rotor model (ARM) of collective rotation is used to search for the correlation between the rotational energy with the asymmetric parameter \gamma_0 for Xe-Pt nuclei. The correspondence of the ratio ROTE/E(2_1^+) vs. R_{4/2}(=E(4_1^+)/E(2_1^+)) and \gamma_0 is used to distinguish between the axially symmetric and triaxial nuclei. The correlation between deformation parameter \beta and \gamma_0 is studied to understand the structure of the nuclei. The \gamma-band energy staggering in low-spin, low-energy spectra of even-even ^{122-124}Xe and ^{124-128}Ba nuclei is also discussed. We have compared our results with experimental data and other theoretical models.
Symmetry And The Order Of Events In Time. The Asymmetrical Order Of Events In Time In A Reversible Energy Converter, Ben-Zion Ginzburg, Randy Wayne
Symmetry And The Order Of Events In Time. The Asymmetrical Order Of Events In Time In A Reversible Energy Converter, Ben-Zion Ginzburg, Randy Wayne
Turkish Journal of Physics
The positive increase of entropy that occurs in irreversible processes has always served as a criterion for distinguishing the past from the future. The unerring ability of the Second Law of Thermodynamics to predict the order of events in time based on a change of entropy in macroscopic systems has led to the concept of the thermodynamical arrow of time. In this paper we analyze a cyclical reversible energy converter, in which thermal energy is converted into useful work without any net change of entropy. While it is usually assumed that time is an outsider in the equations of reversible …

Exactly Solvable Potentials From Decemvirate Power Potential, Nilamoni Saikia
Turkish Journal of Physics
A transformation method is presented which consist of a coordinate transformation and a functional transformation that allow generation of exact analytic bound state solutions of the Schrodinger Green's function equation. The method proposed here, which involves the generation of an exact analytic solution from solvable decemvirate power potential within the framework of Green's functions technique, makes it possible to generate a number of solved quantum systems for original quantum systems with multi-term potentials. The generated quantum systems are in general energy dependent with a single normalized eigenstate. A method has been devised to convert a subset of the generated quantum …

The Influence Of Confinements On The Photon Flux Spectra In Amorphous Silicon Quantum Dots, Moafak Cadim Abdulrida, Nidhal Moosa Abdul-Ameer, Shatha Mohammad Abdul-Hakeem
Turkish Journal of Physics
We have theoretically calculated the photon flux of radiative recombination in amorphous silicon quantum dots (a-SiQDs) at room temperature. These quantum dots have been ranged in their diameter 1 to 4 nm. The convolution of probability density function of deepest energy states of conduction P_C(E) and valence P_V(E) bands within the capture volume was adopted. The behavior of this function can be classified into four regions according to the quantum dot size. The effect of spatial and quantum confinements on the peak value of photon flux must be taken into account. We found that a blue shift is classified by …

Estimation Of Radiological Risk Due To Concentration Of ^{238}U, ^{226}Ra, ^{232}Th And ^{40}K In Soils Of Different Geological Origins In Northern India, Rohit Mehra, Manmohan Singh
Turkish Journal of Physics
Radioactivity of nuclides ^{238}U, ^{226}Ra, ^{232}Th and ^{40}K was measured in soil by \gamma-ray spectrometry using a HPGe detector. A criterion was set in order to analyse soil samples from plain, semi-hilly and hilly areas in northern India. More than three \gamma-ray energy peaks were used for the determination of ^{226}Ra and ^{232}Th activity concentrations to obtain more accurate results. Some of these peaks have interfering energies, which was caused by the limited resolution of the detector, but they were resolved theoretically and used in the analysis because of their significance in reducing the random error to its minimum level. …

Admixture Of Higher Multi-\Hbar\Omega Configurations In The Calculation Of Electron Scattering Form Factors Of Some 1p-Shell Nuclei, Ammar A. Al-Sa'ad
Admixture Of Higher Multi-\Hbar\Omega Configurations In The Calculation Of Electron Scattering Form Factors Of Some 1p-Shell Nuclei, Ammar A. Al-Sa'ad
Turkish Journal of Physics
A semi-microscopic approach that modifies the 1p-shell model wave functions through the admixture of higher p-shells configurations from multi-\hbar\omega model space is submitted in this work. The longitudinal form factors of C2 transitions in ^7Li and ^{15}N, and the transverse form factors of M1 transition in ^{12}C are calculated in the framework of this approach with the emphasis on the reproduction of the second lobe data. It is found that a slight contribution of the higher multi-p-shells with the 1p-shell in the modified initial and/or final states wave functions is sufficient for giving the best description to the form factors …
Heat Capacity Of Trapped Bosons In A Combined Harmonic-Lattice Potential, Azza M. Elbadry
Heat Capacity Of Trapped Bosons In A Combined Harmonic-Lattice Potential, Azza M. Elbadry
Turkish Journal of Physics
In this paper, the heat capacity per particle C(T)/Nk_B of the trapped bosons in a combined harmonic-lattice potential is calculated within the semicalssical approximation. The main effects which can alter the ideal gas are included simultaneously in the present approach. The calculated results show that the heat capacity has a significant dependence on the lattice depth and temperature. Classical results are recovered at sufficiently high temperature, and that it reproduces the Dulong-Petit law type. Moreover, the behavior of the heat capacity in a deep lattice can be used as an indicator for the quantum phase transition superfluid-Mott insulator. It decreases …

Turkish Journal of Physics
IndiumTelluride In_3Te_4 crystal was characterized for electrical conductivity, Hall mobility, carrier concentration, and thermoelectric power (TEP) as a function of temperature in the range 202--526 K this was done with the aid of liquid nitrogen which enabled us to detect the intrinsic behavior. The crystals were prepared by a modified vertical Bridgman technique. Throughout these measurements various physical parameters, such as effective mass of charge carriers, carrier mobility, diffusion coefficient, and relaxation time for both majority and minority carriers were found.

Electromagnetic Energy Conservation With Complex Octonions, Mustafa Emre Kansu, Murat Tanişli, Süleyman Demi̇r
Turkish Journal of Physics
Octonions are the eight dimensional hypercomplex numbers that form a noncommutative and nonassociative division algebra. In this study, a general framework for the real, complex octonions and their algebra are provided by using the Cayley-Dickson multiplication rule between the octonionic basis elements. Maxwell's equations without sources are shown in Gauss units in dimensionless form. The local energy conservation equation, which has been previously defined in a complexified quaternionic form, is similarly rearranged for isotropic media by using the complex octonions. As a result, the terms of density and flow of electromagnetic energy are attained.

Scale Dimension As The Fifth Dimension Of Spacetime, Sergey Fedosin
Turkish Journal of Physics
The scale dimension discovered in the theory of infinite nesting of matter is studied from the perspective of physical implementation of well-studied four-and n-dimensional geometric objects. Adding the scale dimension to Minkowski four-dimensional space means the necessity to use the five-dimensional spacetime.
