The effects of the magnetic field and dielectric screening on the diamagnetic susceptibility of a donor in a quantum well with anisotropic effective mass
(ELSEVIER SCIENCE BV, 2010)
The diamagnetic susceptibility and the binding energy of a hydrogenic donor in a quantum well with different mass anisotropy parameters gamma=m(perpendicular to)/m(parallel to) are investigated in the presence of a magnetic ...
Intense laser field effects on the intersubband optical absorption and refractive index change in the delta-doped GaAs quantum wells
(ELSEVIER SCIENCE BV, 2017)
In this paper, we have investigated the effects of the non-resonant intense laser field on the electronic and optical properties such as linear, nonlinear and the total optical absorption coefficient and refractive index ...
Study of electron-related optical responses in the Tietz-Hua quantum well: Role of applied external fields
(ELSEVIER SCIENCE BV, 2018)
In the present study, we theoretically reported the effects of applied external fields, such as intense laser field and electric and magnetic fields, on the optical absorption coefficient and refractive index changes in ...
Dependence of impurity binding energy on nitrogen and indium concentrations for shallow donors in a GaInNAs/GaAs quantum well under intense laser field
(SPRINGER, 2011)
Within the framework of the effective-mass approximation, using a variational method, we have calculated the effect of intense laser radiation on the binding energy of the shallow-donor impurities in a Ga1-xInxNyAs1-y/GaAs ...
Linear and nonlinear optical absorption in different graded quantum wells modulated by intense laser field
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2012)
The laser field dependence of the linear and nonlinear intersubband optical absorption in different graded quantum wells (GQWs) is investigated in the effective mass approximation. Results obtained show that the position ...
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 ...
Fourier transform technique in variational treatment of two-electron parabolic quantum dot
(IOP PUBLISHING LTD, 2009)
In this work, we propose an efficient method of reducing the computational effort of variational calculation with a Hylleraas-like trial wavefunction. The method consists of introducing integra transforms for the terms as ...
Effects of an intense, high-frequency laser field on the binding energy of excitons confined in a GaInNAs/GaAs quantum well
(ELSEVIER SCIENCE BV, 2012)
The effects of an intense, high-frequency laser field linearly polarized along the growth direction on the binding energy of excitons confined in a GaInNAs/GaAs quantum well is computed for different nitrogen and indium ...
Spin-orbit interaction effects on the optical properties of quantum wires under the influence of in-plane magnetic fields
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2015)
In this work, we studied the effects of in-plane magnetic field and Rashba spin-orbit interaction on the intersubband optical absorption coefficients and changes in refractive index for transitions between the first two ...
The polarizability and the photoionization cross-section under the external fields for donor impurities in quantum well-wire
(WILEY-V C H VERLAG GMBH, 2007)
In this study, we have calculated the donor impurity binding energy, donor impurity related photoionization cross-section and polarizability in symmetric GaAs/Ga1-xAlxAs quantum well-wire as a function of the impurity ...
