Abstract

The electron density distribution is calculated for a doped superlattice with controlled vertical disorder caused by fluctuations of the layer thicknesses (quantum well widths) in the growth direction. At low temperatures, the exchange interaction leads to an increase in the scatter of quantum confinement levels and the formation of a soft gap in the electron density distribution over quantum wells of the superlattice.
