Using the effective mass and parabolic band approximations and a variational procedure we have calculated the combined effects of intense laser radiation, hydrostatic pressure, and applied electric field on shallow-donor impurity confined in cylindrical-shaped single and double GaAs-Ga 1-x Al x As Q
An investigation of the optical properties of a spherical quantum dot (QD) with parabolic confinement potential containing one electron has been performed for the cases with a donor impurity and an acceptor impurity in the presence of an electric field. The oscillator strength between the ground and
The binding energy of a donor impurity in a spherical GaAsΒ±(Ga,Al)As quantum dot with parabolic confinement is calculated as a function of the radius of the quantum dot and as a function of the intensity of an applied electric field. Calculations are performed within the effective-mass approximation
