Electrical Characteristics Of Si Doped With Sb By Laser Annealing, Raid A. Ismail, Aseel A. Hadi Jan 2003

Electrical Characteristics Of Si Doped With Sb By Laser Annealing, Raid A. Ismail, Aseel A. Hadi

Turkish Journal of Physics

Laser induced diffusion of antimony in silicon was obtained using a Nd:YAG pulsed laser. The irradiation of antimony-coated silicon by laser beam allowed melting and diffusion of antimony inside the silicon. Diodes were fabricated. Laser beam energy and substrate temperature played a major role in electrical sheet conductivity I-V, and C-V characteristics of the fabricated diodes. High laser energy reduced the electrical sheet conductivity and dominated the recombination current due to the generation-recombination process and trapping centers. On the other hand, the diffusion current dominated for diodes fabricated under heating conditions of the sample during laser irradiation. The C-V measurements …

Electron Transport Mechanism In Gan/Algan Hemt Structures, Si̇bel Gökden Jan 2003

Electron Transport Mechanism In Gan/Algan Hemt Structures, Si̇bel Gökden

Turkish Journal of Physics

The electron transport mechanism in GaN/AlGaN HEMT (High Electron Mobility Transistors) structures grown with MBE on sapphire substrate was investigated by using the temperature dependence of the Hall coefficient, resistivity, carrier density and Hall mobility. Hall measurements were carried out using Van der Pauw geometry. From the LO-phonon-scattering-limited component of the mobility, we obtain LO phonon energy \hbar \omega \approx 90 meV and the momentum relaxation time of \tau_{m} \approx 4 fs. Also, from the temperature dependence of the 2D carrier density, we obtain the donor activation energy E_{a} \approx 29 meV.

Study Of The Structure And Some Physical Properties Of Sodium-Boro-Phosphate Glasses Containing Antimony And Iron Oxides, Karam Abdel-Aati̇ Ali, Ahmet Gamal El-Din Mostafa Jan 2003

Study Of The Structure And Some Physical Properties Of Sodium-Boro-Phosphate Glasses Containing Antimony And Iron Oxides, Karam Abdel-Aati̇ Ali, Ahmet Gamal El-Din Mostafa

Turkish Journal of Physics

Boro-phosphate glasses containing transition metal oxides are of special interest. Hence, some sodium-Boro-phosphate glasses containing iron and antimony oxides were prepared and investigated. The structural investigation indicated the presence of different borate groups as well as tetragonal phosphate units. Most of the iron cations were found to occupy the low spin Fe^{3 +} in the tetrahedral coordination state. It was observed that some antimony act as network former cations and some others act as bridges between any two adjacent polyhedra. At high antimony oxide content, the formation of some Sb-Fe bonds was also detected. The magnetic susceptibility measurements showed a …

A Study Of Direct Two-Proton Transfer Reactions Using Optical Potential Model, A. K. A. R. Al-Farra Jan 2003

A Study Of Direct Two-Proton Transfer Reactions Using Optical Potential Model, A. K. A. R. Al-Farra

Turkish Journal of Physics

^{12}C, ^{26}Mg(^3He,n) reactions have been studied at high bombardment energy with evaluation of the differential cross sections to the ground and the first excited states evaluated in the framework of the exact finite-range Born approximation (DWBA) calculations using the optical model. With the constraint that bound-state interactions have a Thomas-Fermi spin orbit form, different formations of the bound-state wave functions are explored. The calculated angular distributions are found to be in a good agreement with the experimental data. The present DWBA predictions are normalized to give the best overall fits to the data. The extracted spectroscopic factors are reasonable.

Beliefs About The Appropriate Degree Of Directiveness In The Management Relationship, As Related To Demographic Characteristics, Educational Background, And Organizational Position, Janet L. Pershing Jan 2003

Beliefs About The Appropriate Degree Of Directiveness In The Management Relationship, As Related To Demographic Characteristics, Educational Background, And Organizational Position, Janet L. Pershing

Harold L. Hodgkinson Award for Outstanding Dissertation

Correlations between beliefs about management and age, gender, nationality, level of education, education field, functional area, and hierarchical level were examined. Analyses were conducted at the ecological level and focused on beliefs regarding appropriate degree of directiveness in the managerial relationship. Two thousand staff members of an international intergovernmental organization received an electronically distributed written survey. Factor analysis was used to develop summated rating scales for each independent variables. Differences between subgroup means were then examined using ANOVA or t tests. The strength of the association between the independent variables and a common scale was assessed using eta squared. Directiveness …

Evaluating The Usefulness Of Soil Moisture (Forecasts) In Streamflow Prediction For Central Texas , Mohammed Mahmoud Jan 2003

Evaluating The Usefulness Of Soil Moisture (Forecasts) In Streamflow Prediction For Central Texas , Mohammed Mahmoud

Dissertations, Master's Theses and Master's Reports - Open

The past decade has brought significant advancements in seasonal climate forecasting. However, water resources decision support and management continues to be based almost entirely on historical observations and does not take advantage of climate forecasts. This study builds on previous work that conditioned streamflow ensemble forecasts on observable climate indicators, such as the El Niño-Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO) for use in a decision support model for the Highland Lakes multi-reservoir system in central Texas operated by the Lower Colorado River Authority (LCRA). In the current study, seasonal soil moisture is explored as a climate indicator …

Climatological Study Of Transport To The Pico-Nare Site Using Atmospheric Backward Trajectories, Robert Christopher Owen Jan 2003

Climatological Study Of Transport To The Pico-Nare Site Using Atmospheric Backward Trajectories, Robert Christopher Owen

Dissertations, Master's Theses and Master's Reports - Open

This study developed a transport climatology to the PICO-NARE station, in the central North Atlantic Ocean, using a 40-year set of atmospheric back trajectories. The trajectory set was subjected to a cluster analysis in order to group trajectories into six flow patterns, or clusters. An air flow probability analysis was conducted in conjunction with the cluster analysis in order to determine the source regions for flow to the site. Seasonal differences in the flow patterns were found, which included enhanced westerly flow in the winter, decreased westerly flow in the summer, and spring and fall having moderate westerly flow. The …

Selection Of Chickpea (Cicer Arietinum L.) Genotypes For Resistance To Ascochyta Blight [Ascochyta Rabiei (Pass.) Labr.], Yield And Yield Criteria, Cengi̇z Toker, Hüseyi̇n Çanci Jan 2003

Selection Of Chickpea (Cicer Arietinum L.) Genotypes For Resistance To Ascochyta Blight [Ascochyta Rabiei (Pass.) Labr.], Yield And Yield Criteria, Cengi̇z Toker, Hüseyi̇n Çanci

Turkish Journal of Agriculture and Forestry

Ascochyta blight, caused by Ascochyta rabiei (Pass.) Lab., is the most important disease in the chickpea (Cicer arietinum L.) in many countries, including Turkey. Efforts to control the disease were made using host-plant resistance as the most efficient and economical way. A total of 41 exotic genotypes were evaluated for resistance to A. rabiei and also yield and yield criteria near Antalya in the west Mediterranean region of Turkey in the 2000-2001 and 2001-2002 seasons. After every 2 test lines, the susceptible check ILC 263 was sown. When the susceptible check was completely killed by ascochyta blight, blight severity was …
