Further evidence for electron-electron scattering in aluminum

Abstract

Below 2K, the temperature dependent resistivity of Al is found to be dominated by a term of the form AT2, with a coefficient A which is practically independent of residual resistivity rho 0 for values of rho 0 differing by a factor of 160. This AT2 term is attributed to electron-electron scattering. It is also shown that no simple power law can describe the behaviour of the resistivity between 2K and 4K.
