Comment on "Low-temperature resistivity and thermoelectric ratio of copper and gold"

Abstract
Electron-electron scattering can be observed in the transport properties of simple metals both at low temperatures, where it dominates the temperature-dependent resistivity ρ(T), and at high temperatures where it dominates the deviation of the Lorenz function from the Lorenz number. Comparison of low- and high-temperature data supports the recent tentative identification of an electron-electron term in ρ(T) for Cu. The same analysis also supports a similar identification in Ag and leads us to predict the magnitude of the as yet unobserved effect in Au. The analysis is also applied to the other simple metals for which the low-temperature ρ(T) has been carefully examined, namely K and Al. In K, a measure of consistency can be achieved on the basis of some reasonable assumptions. In Al, the relation between the observed low- and high-temperature data is inconsistent with present theory. A possible mechanism for this inconsistency is suggested.
