Abstract

A general fundamental feature of the high-Tcoxides is a very small value of the Fermi energy. We point out that this leads to peculiar thermodynamic and transport properties in the normal and superconductive states, which in fact require unconventional analysis. We show that the electronic heat capacity can be separated at high temperature and it can be used to determine the electronphonon-coupling constant. The unusual temperature dependences of the kinetic coefficients can also be explained.
