ELECTRON–PHONON SCATTERING AND ELECTRONIC TRANSPORT IN LAYERED STRUCTURES

Abstract

The two-dimensional degenerate electron gas with electron–phonon scattering is analyzed. The normal-phase temperature dependence of the electrical resistivity and the thermo-electrical power are calculated, based on the electron–phonon scattering and other usual ones. Results are compared to those of earlier studies on three-dimensional phonon-limited scattering. Comparison is qualitatively made for several layered materials of interest (MOS, heterostructures, etc.). It occurs that the theory does not seem to apply to YBCO-like Tc superconductors which have a too low Fermi energy with respect to the Debye temperature.
