Abstract
It is shown that in semiconductor superlattices slight fluctuations in the layer thicknesses and alloy compositions are likely to cause strong localization of electronic states. Such localization will hinder miniband formation or band folding expected in an ideal superlattice. The localization tendency can be substantially reduced by decreasing the barrier thickness and/or potential barrier height.Keywords
