Weak Localization Effects On The Electron-Phonon Interaction In Disordered Metals

Weak localization has a strong influence on both the normal and superconducting properties of metals. In particular, since weak localization leads to the decoupling of electrons and phonons, the temperature dependence of resistance decreases with increasing disorder, as manifested by Mooij’s empirical rule. In addition, Testardi’s universal correlation of Tc and the resistance ratio follows. We show that weak localization leads to the similar correction to other physical quantities, such as electronic thermal resistivity, electronic heat capacity, and ultrasonic attenuation, which are controlled by the electron-phonon interaction.
