摘要: We analyze current-voltage characteristics taken on Au-doped indium-oxide films. By fitting a scaling function to the data, we extract electron-phonon scattering rate as of temperature, which yields quadratic dependence temperature from 1K down 0.28K. The origin this enhanced is ascribed mechanism proposed by Sergeev and Mitin.
