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 ...
Interband absorption and exciton binding energy in an inverse parabolic quantum well under the magnetic field
(ELSEVIER SCIENCE BV, 2007)
We have investigated the effects of the magnetic field which is applied perpendicular to the growth direction of the well on the interband absorption and on the binding energy of the excitons in an GaAs/Ga1-xAlxAs inverse ...
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 ...
Optical properties of double quantum wires under the combined effect of spin-orbit interaction and in-plane magnetic field
(ELSEVIER SCIENCE BV, 2016)
In this work, we investigate the intersubband optical absorption coefficients and refractive index changes for transitions between the lower-lying electronic levels of double quantum wires formed by a symmetric, double ...
Binding energy of impurity states in an inverse parabolic quantum well under magnetic field
(ELSEVIER SCIENCE BV, 2007)
We have investigated the effects of the magnetic field which is directed perpendicular to the well on the binding energy of the hydrogenic impurities in an inverse parabolic quantum well (IPQW) with different widths as ...
Linear and nonlinear optical properties in asymmetric double semi-V-shaped quantum well
(ELSEVIER SCIENCE BV, 2015)
In this present work, the effects of the structure parameters such as the right-well width and the rightbarrier height on the linear, third-order nonlinear and total absorption and refractive index changes of asymmetric ...
