Abstract

The conductivity of indium oxide films was studied as a function of k Fl (including kFl<or approximately=1), film thickness, temperature and magnetic field. For sufficiently thin films the authors observe a change from logarithmic to faster temperature dependence below a temperature determined by RSquare Operator. The analogous crossover for thicker samples is shown to depend on kFl. Whether a given system is 'thin' enough for RSquare Operator to be the relevant parameter in this respect is determined by the value of the correlation length xi .
