Electric resistivity and thermoelectric coefficient in layered structures with an anisotropic energy spectrum
Abstract
The temperature dependence of resistivity ρ and thermoelectric coefficient α is studied in terms of the Mott-Davies theory for electronic processes in quasi two-dimensional disordered systems. The existence of a peak in the electron state density and narrow energy bands makes it possible to describe the anomalies in the temperature dependence of α and ρ in high temperature superconducting cuprates based on FeAs.
