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 ...
The high hydrostatic pressure effect on shallow donor binding energies in GaAs-(Ga, Al)As cylindrical quantum well wires at selected temperatures
(ELSEVIER SCIENCE BV, 2011)
We have presented the behavior of a shallow donor impurity with binding energy in cylindrical-shaped GaAs/Ga(0.7)Al(0.3)As quantum well wires under high hydrostatic pressure values. Our results are obtained in the effective ...
Barrier height effect on binding energies of shallow hydrogenic impurities in coaxial GaAs/AlxGa1-xAs quantum well wires under a uniform magnetic field
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2007)
The ground state binding energies of axial hydrogenic impurities in a coaxial cylindrical quantum well wire are reported as a function of the barrier height and the radius of wire in the presence of a uniform magnetic field ...
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 ...
The effect of dielectric constant mismatch on the binding energy of hydrogenic impurities in cylindrical quantum wires
(ELSEVIER SCIENCE BV, 2010)
The ground state binding energy dependency of hydrogenic impurities on dielectric constant mismatch is investigated in cylindrical quantum wires as a function of wire radius and alloy concentration. The calculations are ...
The value of fine-needle aspiration cytology in salivary gland lesions, 1994-2004
(KARGER, 2007)
Objective: Fine-needle aspiration cytology (FNAC) of the salivary gland is a commonly accepted, sensitive and specific technique in the diagnosis of both neoplastic and nonneoplastic lesions of the salivary gland. The aim ...
Linear and nonlinear optical absorption coefficient and electronic features of triple GaAlAs/GaAs and GaInAs/GaAs quantum wells depending on barrier widths
