Popis: | Thermoelectric power measurements have been made on nonstoichiometric α‐Nb2O5 over the temperature range from 300° to 1270°K. The measurements show that, for all compositions in the single‐phase, α‐Nb2O5—x region (0.0012≤x≤0.1545), the majority charge carriers are electrons. These thermoelectric power data have been interpreted in terms of a simple semiconductor exhibiting conduction in a narrow d band with the conduction electrons being assigned an effective mass equal to four times that of the rest mass. |
