S. Katircioglu et S. Erkoc, DEPENDENCE OF RESONANCE STATES ON DOPING LEVEL AND DOPING DISTRIBUTION TYPE IN GAAS GA0.75AL0.25AS SUPERLATTICE, Surface science, 311(1-2), 1994, pp. 120000682-120000686
The electronic structure of a uniformly and modulation-doped GaAs/Ga0.
75Al0.25As superlattice has been investigated by a self-consistent fie
ld calculation within the effective mass approximation for three diffe
rent 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.
