Abstract
Temperature and magnetic field dependence of conductivity in Bi thin films is measured and compared with theories of the localization and the Coulomb interaction between electrons. The anti-localization effect in the case of strong spin-orbit interaction–logarithmic increase of conductivity with decreasing temperature–is found together with the other ln T term due to the interaction effect. From the analysis of the magnetic field dependence the inelastic scattering time is determined to vary as T -1 below 1.5 K and as T -2 above 4 K being consistent with the temperature dependence of conductivity.
