摘要：

Superconducting properties were measured for polycrystalline nearly single-phase samples of Pr1-xCexLaCuO4+delta (PLCCO) (0 less than or equal to x less than or equal to 0.2). Thermoelectric power (S) was found to be negative for all the samples in the temperature range between 50 and 310 K. This evidence clearly indicates that the dominant charge carriers of Pr1-xCexLaCuO4+delta are electrons. (C) 2002 Elsevier Science B.V. All rights reserved.
