Electrical properties of some liquid semiconductors

Abstract

Abstract The electrical conductivity, σ, Hall coefficient, R, and absolute thermoelectric power, S, have been measured for a variety of liquid tellurides and antimonides. For most of these liquids R and S were found to have values typical of metals, although dσ/dT was always observed to be positive. In one case, however, for a liquid whose composition was near to Tl2 Te, |R| was found to be an order of magnitude greater than that for metals. It is suggested that the recent theory of Mott might have particular relevance to the electrical properties of these liquids.
