Frequency Dependence of High-Frequency Transport Properties of Cubic Crystals

Abstract

To the first and second orders in electric and magnetic fields, respectively, isothermal transport properties of a uniform cubic crystal are described by five coefficients. With sinusoidally varying electric field, the co-efficients are complex functions of frequency. This paper discusses the frequency dependence of the coefficients for the case of electrons occupying states near nondegenerate energy minima arranged with cubic symmetry. The frequency dependence is found to be strongly influenced by the mechanism of the electron-lattice interaction.
