PHONON-MEDIATED ELECTRON-ELECTRON SCATTERING IN ALUMINUM - A 1ST DETAILED CALCULATION

A microscopic calculation of the phonon mediated electron-electron sca ttering rate (SR) has been performed with realistic Fermi surface and phonon spectrum for the first time. This confirms the results of earli er approximate calculations 1,2 that the contributions from exchange o f virtual phonons dominates the usual Coulomb interaction. The dense m esh of our calculation reveals a surprisingly strong (20 to 1) anisotr opy for the T2 coefficient of the electron-electron SR. We also obtain a more complete picture of the temperature dependent electron-phonon SR.
