摘要

We have studied the electronic wave propagation through a one-dimensional random dimer system in the presence of non-linear interactions. By investigating the scaling dependence of the extended states bandwidth, the non-linear interaction is found to improve the electronic conduction in such systems. It is also found that the resonance energy states in these systems are shifted depending on the kind of interaction. Further investigations are provided on the localization transition around these resonances. (c) 2006 Elsevier B.V. All rights reserved.
