| heal.abstract | Charge depletion from 20 monolayers of n(+)-In0.53Ga0.47As, uniformly doped with Si donors and embedded within Be-doped In0.53Ga0.47As, has been studied at 1.2 K by magnetotransport measurements. Electron subband energies and densities associated with the n(+)-In0.53Ga0.47As potential well prove sensitive to the presence of the acceptors at concentrations up to 3 X 10(16) cm(-3). Agreement between the experimental data and the electronic subband structure calculated self-consistently by solving the one-dimensional Schrodinger and Poisson equations is excellent. The results suggest that intentional background acceptor doping could be a useful mechanism for tuning subband fillings and energies in potential wells formed by highly confined donors.
