摘要：

Many superconducting cuprates show a parabolic variation of T(c) with hole concentration p, there being a minimum and a maximum hole concentration for superconductivity. Thermoelectric power (TEP) measurements reported here as a function of p for a number of oxides reveal several important trends: (1) close similarities in the TEP of several compounds and a change in sip of the room-temperature TEP near the maximum T(c), (2) continuity in the TEP when doping across the two superconducting-nonsuperconducting boundaries, and (3) a universal correspondence of the room-temperature TEP with p over the whole range of doping.
