Abstract
Conduction by classical charge carriers is investigated for a one-dimensional system interrupted by barriers with a random distribution of activation energies. Under certain conditions the transport properties are dominated by disorder, and the model predicts an anomalous low-frequency conductivity , with , for , and a mobility transition at . The model is shown to describe recent experiments on the one-dimensional superionic conductor hollandite ().
