A self-consistent method for determining electron correlations and electron scattering from disorder is used to calculate electron mobilities in disordered quantum wires of finite diameter. We look at electron localization in terms of mean free paths. We find cases where the mobility drops toward zero, and the mean free path is of the order of the average electron spacing, corresponding to strong localization. We determine the peak mobility as a function of impurity density and wire diameter.

Abstract
A self-consistent method for determining electron correlations and electron scattering from disorder is used to calculate electron mobilities in disordered quantum wires of finite diameter. We look at electron localization in terms of mean free paths. We find cases where the mobility drops toward zero, and the mean free path is of the order of the average electron spacing, corresponding to strong localization. We determine the peak mobility as a function of impurity density and wire diameter.File in questo prodotto:
