Abstract

Abstract The electrical resistivity arising from electron-electron Umklapp scattering is calculated at low temperatures for the anisotropic but two-dimensional charge-transfer complex (TMTSF) 2PF 6. Also, we consider a specular scattering correction to a recent one-phonon scattering mechanism and find a significant change in the temperature dependent behavior of the resistivity. Finally an exact solution is obtained for the resistivity arising from two-libron scattering and is found to give a small contribution at low temperatures. Comparing these results with recent data, we find that the electron-electron mechanism yields the most satisfactory agreement at low temperatures, while contributions from the other two mechanisms may not be negligible at high temperatures.
