Abstract
We have studied the temperature and magnetic field dependence of conductance in the two dimensional electron system of indium-tin-oxide films at temperatures between 1.5 and 300 K and up to the magnetic field of 100 kOe. Evidence for localization as well as correlation effects, and that for two-to-three dimensional transition induced by the magnetic field are clearly observed. By precisely fitting the experimental data to the available theories, localization parameters α T and α H as well as the temperature dependence of the inelastic scattering time τ e are deduced. For thick films, localization features of the three dimensional system are also observed.
