摘要：

We study the localisation properties of the eigenstates in the Kronig-Penney model with weak compositional and structural disorder. The main result is an expression for the localisation length that is valid for any kind of self- and inter-correlations of the two types of disorder. We show that the interplay between compositional and structural disorder can result in anomalous localisation. (C) 2008 Elsevier B.V. All rights reserved.
