High Tc Cuprates

The van Hove model of a two-dimensional band structure with nearest-neighbor and next-nearest-neighbor hopping integrals is used to account for unusual temperature and doping dependence of the thermoelectric power (TEP) in cuprate superconductors. It is shown that the present theory can reproduce global trends of TEP data, including a positive peak of TEP in the underdoped regime, a decrease in TEP with increasing doping, a change in sign of TEP nearby the optimal doping, and an approximately linear decrease in TEP with temperature.
