Competition between the Electron-Electron and Electron-Phonon Mechanisms in the Electrical and Thermal Resistivities of Simple Metals

  • W. E. Lawrence

Abstract

The purpose of this paper is to discuss the use of the thermal (and electrical) resistivities as tools for studying the electron-electron interaction in metals. We focus on the simple and noble metals, where only tentative evidence exists at present, and we hope to indicate where further evidence might best be sought. The difficulty in observing electron-electron scattering is that it tends to be dominated by electron-phonon scattering, particularly in the simple metals. To observe the electron-electron mechanism, one is thus pushed to extremes of temperature (high or very low) where it tends to compete more favorably: Electron-electron contributions to p and WT increase quadratically with temperature, while the electron-phonon contributions increase linearly at high temperatures (T ≳ θD), but much faster (ρ ~ T5 and WT ~ T3) at extremely low temperatures T << θD. The competition in the high and low temperature regimes will be discussed in sections II and III.
