Abstract
We study the lateral transport of two-dimensional randomly layered media in the presence of isotropic randomness. The hopping anisotropy is also included. Equilibration length and channel occupation number are calculated by using both the recursive Green's-function method and the rate-equation approach. Our results show clearly a transition from ergodic to nonergodic transport as the number of layers increases. This describes a dimensional-crossover behavior from two-dimensional-like anisotropic hopping systems to one-dimensional-like randomly layered media.
