Abstract

The effect of weak anti-localization, electron interactions and superconducting fluctuations on the transport properties of disorder Nb_0.53Ti_0.47-Ge multilayers were studied. The temperature dependence of the inelastic scattering time was found to be τ_in ∼ T^-1±0.25 and τ_in ∼ T^-1.75±0.25 for temperatures lower and higher than ∼ 6K, repectively for a sample with thick Ge layers. The effect of the Ge thickness on the prefacter A in the expression R□ ∼ ln T may arise from an interlayer electron-phonon process.
