Temperature Dependence of the Hall Coefficient of Thin Films

Abstract

A theoretical expression for the temperature coefficient βRH of the Hall coefficient R_HF of metallic films is deduced from the Fuchs–Sondheimer conduction model. The general expression takes into account the deviation introduced by the geometrical limitation of the mean free path. This is negligible for relatively thick films (k ≥ 1 for p = 0) and agrees with experiments previously reported by other authors.
