摘要：
In this work we have studied systematically the effect of fluctuations in thickness and depth of the well as well as in the thickness of the barrier in semiconductor superlattices. Our results show that the main effect of fluctuations is to break down the whole superlattice into subsets. Localization occurs when there are no degenerate states among the subsets, regardless of symmetry considerations.
