Abstract

We calculate the localization lengths for lattice fermions with random gap in two dimensions. This is done by means of the transfer matrix approach. Numerical results are analyzed for finite-size scaling and they exhibit a metal-insulator and a insulator-insulator transition. At these transitions we calculate the critical exponent of the localization length.
