The thermopower in single crystals of YBa/sub 2/Cu/sub 3/O/sub 7/ has quite different behavior in the in-plane (S/sub a//sub b/) and out-of-plane (S/sub c/) directions. S/sub a//sub b/ is positive and shows a characteristic peak above T/sub c/ while S/sub c/ (also positive) increases strongly with temperature with a dependence which may be fitted to T/sup 1.65/ or AT+BT/sup 2/. We discuss the role of phonon drag and band filling in affecting the sign of the in-plane thermopower.
