Linear and nonlinear optical properties in the terahertz regime for multiple-step quantum wells under intense laser field: Electric and magnetic field effects
(ELSEVIER SCIENCE BV, 2018)
We present a theoretical study on the linear and nonlinear optical properties in AlrGa1-rAs/GaAs asymmetric multiple step quantum wells (AMSQW) under the effects of a non-resonant intense laser field (ILF), electric, and ...
Third-harmonic generation of a laser-driven quantum dot with impurity
(ELSEVIER SCIENCE BV, 2018)
The third-harmonic generation (THG) coefficient for a laser-driven quantum dot with an on-center Gaussian impurity under static magnetic field is theoretically investigated. Laser field effect is treated within the ...
Binding energy of donor impurity states and optical absorption in the Tietz-Hua quantum well under an applied electric field
(ELSEVIER SCIENCE BV, 2018)
For a quantum well which has the Tietz-Hua potential, the ground and some excited donor impurity binding energies and the total absorption coefficients, including linear and third order nonlinear terms for the transitions ...
Effects of Geometry on the Electronic Properties of Semiconductor Elliptical Quantum Rings
(NATURE PUBLISHING GROUP, 2018)
The electronic states in GaAs-AlxGa1-xAs elliptically-shaped quantum rings are theoretically investigated through the numerical solution of the effective mass band equation via the finite element method. The results are ...
Electron-related optical responses in Gaussian potential quantum wells: Role of intense laser field
(ELSEVIER SCIENCE BV, 2018)
A theoretical study of the effects of non-resonant intense laser field on the optical response in a Gaussian potential quantum well is performed in the framework of the effective mass approximation. The obtained results ...
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 ...
Electric and magnetic field modulated energy dispersion, conductivity and optical response in double quantum wire with spin-orbit interactions
(ELSEVIER SCIENCE BV, 2018)
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 ...
