TEMPERATURE DEPENDENCE OF THE HOPPING HALL MOBILITY IN SPATIALLY AND ENERGETICALLY DISORDERED SYSTEMS

Abstract
We present an averaging procedure for the calculation of the Hall mobility for spatial and energetical disordered hopping systems in the framework of percolation theory. For a constant density of states function the temperature dependence of the Hall mobility follows a T -1/4- law with a slope which is by a factor of about 8/3 smaller than that of the conductivity. The comparison with the self consistent Random Walk Theory of transport yields qualitatively the same results.
