Abstract

The temperature-dependent resistivity of single-crystal K3C60 is studied from the point of view of electron-electron and electron-phonon scattering. The electron-phonon analysis suggests that conventional electron-phonon coupling would be sufficient to account for the superconductivity, with contributions to the coupling from both high-frequency intraball and low-frequency interball modes. The resistivity was also compared to a quadratic temperature dependence, suggestive of electron-electron scattering at anomalously high temperatures.
