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 hydrostatic pressure and temperature effects on hydrogenic impurity binding energies in GaAs/InxGa1-xAs/GaAs square quantum well
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2016)
We have calculated the ground state binding energy using variational methods and the effective mass approximation for the hydrogenic impurity in square quantum well structure made up of GaAs/InGaAs/GaAs epilayers under the ...
Shallow impurity binding energy in lateral parabolic confinement under an external magnetic field
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2008)
We have described the calculation of hydrogenic impurity binding energies in cylindrical GaAs-Ga(1-x)Al(x)As quantum well wires (QWWs) with lateral parabolic confinement in the presence of an axial magnetic field. The ...
Modeling of reflectance properties of ZnO film using artificial neural networks
(NATL INST OPTOELECTRONICS, 2015)
A ZnO thin film was prepared on a p-Si (100) substrate by using a pulsed filtered cathodic vacuum arc deposition system (PFCVAD). Specular reflectance, a nondestructive technique, can be used to measure thickness, refractive ...
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 ...
The magnetoexciton binding energy dependency on aluminium concentration in cylindrical quantum wires
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2009)
A calculation of the binding energy of an exciton confined in cylindrical quantum wires of GaAs surrounded by (Ga, Al) As in the presence of a uniform magnetic field is reported as a function of wire radius, potential ...
Correlations between the Expression Levels of Micro-RNA146b, 221, 222 and p27Kip1 protein mRNA and the Clinicopathologic Parameters in Papillary Thyroid Cancers
(JOHANN AMBROSIUS BARTH VERLAG MEDIZINVERLAGE HEIDELBERG GMBH, 2014)
Context: It has been shown that miRNA 221, 222 and 146b are increasingly expressed while p27(Kip1) is suppressed in papillary thyroid cancer (PTC). Objective: We investigated the association between the disease recurrence ...
Electrical performance of InAs/AlSb/GaSb superlattice photodetectors
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2016)
Temperature dependence of dark current measurements is an efficient way to verify the quality of an infrared detector. Low dark current density values are needed for high performance detector applications. Identification ...
Nonlinear Optical Rectification, Second and Third Harmonic Generations in Square-Step and Graded-Step Quantum Wells under Intense Laser Field
(IOP PUBLISHING LTD, 2019)
For square-step quantum wells (SSQWs) and graded-step quantum wells (GSQWs), the nonlinear optical rectification (NOR), second harmonic generation (SHG) and third harmonic generation (THG) coefficients under an intense ...
The hydrostatic pressure and temperature effects on hydrogenic impurity binding energies in lattice matched InP/In0.53Ga0.47As/InP square quantum well
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2017)
The on-center shallow-donor impurity binding energy in lattice matched InP/In0.53Ga0.47As square quantum well structure have been theoretically investigated using effective mass and variational techniques. The effects of ...
