โœฆ Synopsis


A model calculation shows that phonon-induced interband scattering of carriers from a low-mass band into a second, high-mass band separated by a distance qo in the reciprocal lattice can produce a saturating term in the electrical resistivity at high temperatures. A balance may occur between the increasing number of phonons and the decreasing number of carriers in appropriate states for scattering by this process if the relevant phonons have only a narrow spread in energies. The application of this analysis to V3Si is presented.
