Abstract
The recent proposal of scattering by fluctuations of polarization energy is used to calculate the difference in conductivity between the commensurate and the incommensurate phases. It is shown that this difference increases when higher pressures are required to achieve commensurability. Another effect of polarization energy is to increase the magnitude of second-order electron-phonon scattering relative to first-order scattering at ambient pressure. However, when the pressure is increased, the contribution to the resistivity from second-order electron-phonon scattering decreases with pressure much more rapidly than the contribution to the resistivity from first-order electron-phonon scattering until, at sufficiently high pressures, the first-order electron-phonon scattering is dominant.
