A theoretical study of chemical doping and width effect on zigzag graphene nanoribbons
Pekoz, Rengin; Erkoç, Şakir (Elsevier BV, 2009-12-01)
The energetics and the electronic properties of nitrogen- and boron-doped graphene nanoribbons with zigzag edges have been investigated using density functional theory calculations. For the optimized geometry configurations, vibrational frequency analysis and wavefunction stability tests have been carried out. Different doping site optimizations for a model nanoribbon have been performed and formation energy values of these sites revealed that zigzag edgesite for both of the dopants were the most favorable ...
Study on the long wavelength SiGe/Si heterojunction internal photoemission infrared photodetectors
Aslan, B; Turan, Raşit; Liu, HC (Elsevier BV, 2005-10-01)
The theory of internal photoemission in semiconductor heterojunctions has been investigated and the existing model has been extended by incorporating the effect of different effective masses in the active region and the substrate, nonspherical-nonparabolic bands, and the energy loss per collision. Photoresponse measurements on Si1-xGex/Si heterojunction internal photoemission (HIP) infrared photodetectors (IP) have shown that they are fit well by the theory. Qualitative model describing the mechanisms of ph...
The self-consistent calculation of a spherical quantum dot: A quantum genetic algorithm study
Sahin, M; Tomak, Mehmet (Elsevier BV, 2005-08-01)
In this study, we have calculated the subband energy level, potential profile, and the corresponding wavefunction and chemical potential for different temperatures and donor concentrations in a spherical quantum dot self-consistently. We have also investigated the effect of exchange-correlation potential on the energy levels. In addition, we have checked the applicability of quantum genetic algorithm to a realistic self-consistent quantum dot problem. In all computations, the penetration of wavefunction to ...
Investigation of the structural, magnetic, and cooling performance of AlFe thin film and AlFeGd nanometric giant magnetocaloric thin films
Pat, Suat; Bayer, Özgür; Akay, Sertan Kemal; Mohammadigharehbagh, Reza; Kaya, Metin (Springer Science and Business Media LLC, 2021-02-01)
Giant magnetocaloric thin films are promising materials for new generation energy-efficient cooling systems. To investigate the cooling performance of AlFe and AlFeGd alloys, thin films have been deposited onto a glass substrate by thermionic vacuum arc (TVA) deposition system. TVA is a physical vapor deposition technology; it works in high vacuum and low-temperature conditions. AlFe and AlFeGd thin films are of significant importance for giant magnetocaloric materials. The surface and magnetic properties o...
On the theory of internal photoemission in heterojunctions
Aslan, B; Turan, Raşit (Elsevier BV, 2005-08-01)
The theory of internal photoemission in semiconductor heterojunctions has been reviewed and the existing model has been extended by incorporating the effects of the difference in the effective masses in the active region and the substrate, non spherical-nonparabolic bands, and the energy loss per collisions. This complete model has been applied to describe the experimental results obtained from Si1-xGex/Si heterojunction infrared photodetectors. The barrier heights (correspondingly the cut-off wavelengths) ...
