Abstract

The CPA d. c. electrical conductivityσ for a bcc based random binary substitutional alloy with long range ordering is determined for a single band model with diagonal disorder and arbitrary alloy parameters. The CPA vertex corrections toσ vanish, off-diagonal elements of the Green function are most important. The conductivity obeys general symmetries with respect to alloy parameters and can be brought to closed form resembling the standard expressionσ = ne2τ/m. To interpret various terms inσ correctly, limits with available Boltzmann equation solutions are analyzed in detail.
