Measurements and interpretation of the electrical resistivity and Hall coefficient in polycrystalline gold films: Part II

Abstract

At room temperature the Hall coefficient is a linear function of the intrinsic resistivity of gold films. This linearity can be explained in terms of the Volger-Bube mosaic theory with some modifications. Theoretical predictions of the temperature dependence of the phonon contribution to the Hall coefficient in thin films explain the observed variation of the latter with temperature in the range 50–300 K. In conclusion, combination of the mosaic theory and the size effect theory of Sondheimer allows a fair interpretation of the resistivity and Hall coefficient of polycrystalline gold films.
