摘要：

We study the effect of correlations between impurity potentials in different layers on the Coulomb drag in a double-layer electron system. It is found that for strongly correlated potentials the drag in the diffusive regime is substantially enhanced compared to what is conventionally predicted. The appropriate experimental conditions are discussed, and the new experiments are suggested.
