Metal-insulator transitions in anisotropic two-dimensional systems
Metal-insulator transitions in anisotropic two-dimensional systems
Several phenomena related to the critical behaviour of non-interacting electrons in a disordered 2d tight-binding system with a magnetic field are studied. Localization lengths, critical exponents and density of states are computed using transfer matrix techniques. Scaling functions of isotropic systems are recovered once the dimension of the system in …
