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 ...
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 and optical absorption of donor impurity states in "12-6" tuned GaAs/GaAlAs double quantum well under the external fields
(ELSEVIER SCIENCE BV, 2019)
We have investigated the binding energies of the s-symmetric ground and first excited shallow donor impurity states and the total 1s -> 2s absorption coefficient, including the first and third order corrections, in "12-6" ...
The effects of temperature and hydrostatic pressure on the photoionization cross-section and binding energy of impurities in quantum-well wires
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2010)
Using a variational approach, we have calculated the donor impurity related photoionization cross-section and impurity binding in GaAs/GaAlAs quantum-well wires under different temperature and hydrostatic pressure conditions. ...
Electronic band structure of GaAs/AlxGa1-xAs superlattice in an intense laser field
(ELSEVIER SCIENCE BV, 2012)
We perform theoretical calculations for the band structure of semiconductor superlattice under intense high-frequency laser field. In the frame of the non-perturbative approach, the laser effects are included via laser-dressed ...

Within the framework of effective-mass approximation, we have calculated theoretically the effects of hydrostatic pressure and doping concentration on subband structure and optical transitions in modulation-doped ...
Effects of applied electromagnetic fields on the optical transitions in a V-shaped quantum well
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2013)
In this study, the interband optical transitions and the binding energy of an exciton in a GaAs/Ga1-xAlxAs V-shaped quantum well (VQW) under the electric and magnetic fields are calculated. The calculations were performed ...
Electric and magnetic field modulated energy dispersion, conductivity and optical response in double quantum wire with spin-orbit interactions

We study the influence of electric field on the electronic energy band structure, zero-temperature ballistic conductivity and optical properties of double quantum wire. System described by double well anharmonic confinement ...
Intense laser effects on donor impurity in a cylindrical single and vertically coupled quantum dots under combined effects of hydrostatic pressure and applied electric field
(ELSEVIER SCIENCE BV, 2010)
Using the effective mass and parabolic band approximations and a variational procedure we have calculated the combined effects of intense laser radiation, hydrostatic pressure, and applied electric field on shallow-donor ...
