Structure of the Scattering Diagrams for Conductivity in Random Binary Alloys and the Self-Consistent CCPA

摘要

The augmented space scattering diagrams for the conductivity for random binary alloys have been examined in detail. Within a CCPA it is seen that in addition to the 'uncorrected' conductivity calculated from averaged currents there are three types of corrections: the vertex correction (non-vanishing except in the 1CPA with diagonal disorder), the corrections to the averaged current and a non-separable correction term. A tractable graphical method for obtaining these corrections is described and an application is made to a simple, three-dimensional alloy model. (Atomindex citation 16:075979)
