摘要：

We study transport properties in a coupled double-plane system with one pure and the other random, in the presence of a transverse random magnetic field. The localization length and conductance of the system are calculated by using the finite-size scaling method combined with transfer matrix technique. We find that in the scaling transformation there is a set of fixed points in a continuous line, indicating that the system undergoes a disorder-driven Kosterlitz-Thouless-type metal-insulator transition.
