Donor Impurity-Related Optical Absorption in GaAs Elliptic-Shaped Quantum Dots
(HINDAWI LTD, 2017)
The conduction band and electron-donor impurity states in elliptic-shaped GaAs quantum dots under the effect of an externally applied electric field are calculated within the effective mass and adiabatic approximations ...
Optical coefficients in a semiconductor quantum ring: Electric field and donor impurity effects
(ELSEVIER SCIENCE BV, 2016)
The electron states in a two-dimensional quantum dot ring are calculated in the presence of a donor impurity atom under the effective mass and parabolic band approximations. The effect of an externally applied electric ...
Electronic structure and optical properties of triangular GaAs/AlGaAs quantum dots: Exciton and impurity states
(ELSEVIER SCIENCE BV, 2016)
Electronic structure and optical properties in equilateral triangular GaAs/Al0.3Ga0.7As quantum dots are studied extensively. The effects of donor and acceptor impurity atoms positioned in the orthocenter of the triangle, ...
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 Raman scattering in a double quantum well tuned by an external nonresonant intense laser field
(ELSEVIER SCIENCE BV, 2017)
In this work we shall present a study of inelastic light scattering involving inter-subband electron transitions in coupled GaAs-(Ga,AI)As quantum wells. Calculations include the electron related Raman differential cross ...
The effects of intense laser field and applied electric and magnetic fields on optical properties of an asymmetric quantum well
(ELSEVIER SCIENCE BV, 2015)
This paper presents the results of the theoretical study of the effects of non resonant intense laser field and electric and magnetic fields on the optical properties (the linear and third order nonlinear refractive index ...
