Abstract
Residual resistivities of alloys for were calculated from first principles using the Korringa-Kohn-Rostoker coherent-potential approximation and yielded quantitiative agreement with experiment with no adjustable parameters. Some aspects of Mott's model are confirmed, but the sheet velocities and lifetimes vary in a surprising manner with concentration because of the energy dependence of the disorder self-energy at the top of the -band complex. These variations are analogous to electron-phonon mass and lifetime renormalization.
