Interband transitions dependent on indium concentration in Ga1-xInxAs/GaAs asymmetric triple quantum wells
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2018)
In this paper, the optical and electronic properties of asymmetric triple quantum well (ATQW) structures are studied depending on the indium concentrations while quantum well (QW) thicknesses and barrier widths are kept ...
Simulation of Highly Reflective GaN/AlxGa1-xN Distributed Bragg Reflector Structure for UV-Blue LEDs
(AMER SCIENTIFIC PUBLISHERS, 2018)
In this study, we showed theoretically enhanced reflectance characteristics of nitride based blue Light Emitting Diode (LED) by adding GaN/AlxGa1-xN Distributed Bragg Reflector (DBR) between n-contact layer and GaN buffer ...
Sandwich method to grow high quality AlN by MOCVD
(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 ...
The effect of barrier width on the electronic properties of double GaAlAs/GaAs and GaInAs/GaAs quantum wells
(ELSEVIER SCIENCE BV, 2018)
In this study, the electronic properties of symmetric and asymmetric double Ga1-xAlxAs/GaAs and Ga(1-x)ln(x)As/GaAs quantum wells have been investigated depending on the barrier width. Using the effective mass approach, ...
Microstructural Evolution of MOVPE Grown GaN by the Carrier Gas
(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 ...
The investigation of quantum efficiency constituents of InAs/AlSb/GaSb based N structure type-II SL photodetectors with InAlAs interface
(IOP PUBLISHING LTD, 2018)
We report on the optical properties of InAs/AlSb/GaSb based Type-II superlattice N-structure with p on n configuration. The detector structure is designed to operate in the mid wavelength infrared range with 50% cut-off ...
