Electron Transport in Amorphous Materials. I

Abstract

It is shown that, when scattering from uncorrelated sets of scatterers is properly considered in a one-electron plane-wave representation, the expectation value of the electron velocity is expressed as an infinite hierarchy of time-dependent exponentials. The lowest-order correction to the free-electron Hall constant, which was incorrectly derived in a recent paper, is rederived and the error corrected.
