Electron-phonon scattering and electronic transport in layered structures

The two-dimensional degenerate electron gas with electron-phonon scattering is analyzed. The normal-phase temperature dependence of the electrical res istivity and the thermo-electrical power are calculated, based on the elect ron-phonon scattering and other usual ones. Results are compared to those o f earlier studies on three-dimensional phonon-limited scattering. Compariso n is qualitatively made for several layered materials of interest (MOS, het erostructures, etc.). It occurs that the theory does not seem to apply to Y BCO-like T-c superconductors which have a too low Fermi energy with respect to the Debye temperature.
