Anisotropic quasiparticle properties in aluminum

The electron-phonon interaction in aluminum was studied using Fermi-surface-fitted 4-OPW electron states, a realistic phonon spectrum, and integration mesh-density varying with local Fermi surface curvature. The resulting electron mass enhancement lambda and thermal scattering rate tau/sup -1/ are evaluated as functions of position on the Fermi surface. It was found that the agreement between observed and calculated cyclotron masses is improved by the use of an anisotropic effective mass enhanc… more
