Electron-related optical responses in triple delta-doped quantum wells
(TAYLOR & FRANCIS LTD, 2019)
A detailed theoretical study on the electron-related optical responses in triple delta-doped GaAs quantum wells in the presence of non-resonant, monochromatic intense laser field is presented. For this purpose, we first ...
Position-dependent mass effects on the optical responses of the quantum well with Tietz-Hua potential
(ELSEVIER GMBH, 2019)
In the present study we have investigated the bound energy levels and intersubband optical transitions in the Tietz-Hua quantum well for a spatially varying effective mass distribution. The energy levels and eigenfunctions ...
Morse quantum well modulated by nonresonant intense laser field: Binding energy and optical absorption related to shallow donor impurities
(ELSEVIER GMBH, 2019)
Binding energies of the lowest two s-symmetric impurity states and linear, third order nonlinear, and total optical absorption coefficients corresponding to the 1s -> 2s transitions for electrons in a Morse quantum well ...
Electronic states in GaAs-(Al, Ga) As eccentric quantum rings under nonresonant intense laser and magnetic fields
(NATURE PUBLISHING GROUP, 2019)
The features of the electron energy spectrum in eccentric two-dimensional GaAs-AlGaAs quantum rings of circular shape are theoretically investigated taking into account the effect of externally applied magnetic and intense ...
Nonlinear optical properties of triple delta-doped quantum wells: The impact of the applied external fields
(ELSEVIER GMBH, 2019)
In the present paper, we theoretically investigate the effect of applied external fields, such as electric, magnetic, and intense terahertz laser fields on the optical absorption and the relative refractive index change ...
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" ...
