The hydrostatic pressure and temperature effects on the binding energy of magnetoexcitons in cylindrical quantum well wires
Baser, P.; Karki, H. D.; Demir, I.; Elagoz, S. (ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2013)We have calculated the binding energy for the ground state of a heavy-hole exciton in GaAs/Ga0.7Al0.3As cylindrical quantum well wires (CQWWs) under the action of a hydrostatic pressure, temperature and magnetic field. The ... -
Microstructural Evolution of MOVPE Grown GaN by the Carrier Gas
Demir, I.; Altuntas, I.; Kasapoglu, A. E.; Mobtakeri, S.; Guer, E.; Elagoz, S. (PLEIADES PUBLISHING INC, 2018)We report the effect of total carrier gas flow of GaN during both GaN nucleation layer and high temperature GaN growth steps on structural, optical, electrical and morphological properties. The formation of dislocations ... -
Sandwich method to grow high quality AlN by MOCVD
Demir, I.; Li, H.; Robin, Y.; McClintock, R.; Elagoz, S.; Razeghi, M. (IOP PUBLISHING LTD, 2018)We report pulsed atomic layer epitaxy growth of a very high crystalline quality, thick (similar to 2 mu m) and crack-free AlN material on c-plane sapphire substrates via a sandwich method using metal organic chemical vapor ...
