Abstract

The electronic structure of a uniformly and modulation-doped GaAs/Ga0.75Al0.25As superlattice has been investigated by a self-consistent field calculation within the effective mass approximation for three different doping concentrations. It has been found that the resonance state energies show a strong dependence on the doping level and the doping distribution type of the superlattice.
