Roy Ceder, Oded Agam, and Zvi Ovadyahu
TL;DR
This study investigates the non-ohmic electrical behavior and energy relaxation in diffusive two-dimensional metals, revealing a quadratic temperature dependence of electron-phonon scattering rates in Au-doped indium-oxide films.
Contribution
It provides experimental evidence for the Sergeev and Mitin mechanism causing enhanced electron-phonon scattering at very low temperatures.
Findings
Electron-phonon scattering rate scales quadratically with temperature.
Scaling analysis effectively extracts scattering rates from I-V data.
Results support the Sergeev and Mitin theoretical model.
Abstract
We analyze current-voltage characteristics taken on Au-doped indium-oxide films. By fitting a scaling function to the data, we extract the electron-phonon scattering rate as function of temperature, which yields a quadratic dependence of the electron-phonon scattering rate on temperature from 1K down to 0.28K. The origin of this enhanced electron-phonon scattering rate is ascribed to the mechanism proposed by Sergeev and Mitin.
