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 ...
