We study the effects of screening on the binding energy of positively and negatively charged impurities in the quasi-one-dimensional electron gas. We assume a parabolic confinement for the electron gas. Many-body effects beyond the random-phase approximation and the valley degeneracy are taken into
The conduction and valence subband energies in the presence of an electric field are calculated using the fifth-order Runge-Kutta method. The binding energies of shallow donors, acceptors and excitons in finite-barrier GaAs/Ga 1-x Al x As quantum wells are then obtained variationally in the presence
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
