    Abstract

    It is shown that the Seebeck coefficient of a semiconductor against copper can be determined in terms of that for a copper-constantan thermocouple by means of a rapid potentiometric measurement. Values obtained for typical samples of bismuth telluride alloy, using the apparatus that is described, are compared with those given by a conventional method and indicate that the technique is perfectly satisfactory.
