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 ...
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 intense laser field on optical responses of n-type delta doped GaAs quantum well under applied electric and magnetic fields
(ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2018)
This work presents the results of the theoretical study of the effects of non-resonant intense laser field, electric and magnetic fields on optical responses of GaAs n-type delta-doped quantum well associated to the electron ...
Impurity-related optical response in cylindrical quantum dots with a delta-doped axial potential under an intense laser field
(PERGAMON-ELSEVIER SCIENCE LTD, 2018)
A theoretical study of the effects of a nonresonant intense laser field on the absorption coefficients and refractive index changes for a two-level system associated with transitions from the 1S -like impurity state to the ...
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 ...
The effect of hydrostatic pressure on subband structure and optical transitions in modulation-doped quantum well
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011)
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 ...
Intense laser field effects on the third-harmonic generation in a quantum pseudodot system
(ELSEVIER SCIENCE BV, 2017)
In this research, we present the effects of high-frequency intense laser field on the third-harmonic generation associated with intersubband transitions in a two-dimensional quantum pseudodot system subjected to an uniform ...
