摘要：

Electronic density of states, mean-square velocity, and Drude plasma energy are computed from previously reported energy bands for Nb3Ge and Nb3Al. These results, together with the empirical electron-phonon coupling constant deduced from the high superconducting Tc, are used to analyze resistivity. Extremely short phonon-limited mean free paths are found. Qualitative and quantitative ideas of saturating resistivity are consistent with our results. © 1978 The American Physical Society.
