ELECTRON AND PHONON TRANSPORT
ELECTRON AND PHONON TRANSPORTIn the preceding chapter on solid properties, we relied on the Drude-Sommerfeld model, which assumes that electrons are completely free and the Fermi surface is spherical and isotropic in all directions of the wavevector. While the concepts of electronic band structures and phonon dispersion in real solids were often mentioned, we have deliberately avoided any details. It is hoped that the free-electron model will help readers gain an intuitive picture of electrons without a deep knowledge of solid state physics. Note that the free-electron model is applicable only for metals, usually good conductors, and cannot be applied to semiconductors. The Sommerfeld theory, albeit successful in…
