Electrical Properties of Liquid Te–Se Mixtures at High Temperatures and High Pressures

Abstract

The electrical conductivity σ and the thermoelectric power S have been measured for liquid Te–Se mixtures in a wide temperature and pressure range. Substantial changes in σ and S are induced by a slight application of pressure. The region where such changes occur is determined can the concentration-temperature plane. It is suggested that the observed semiconductor to metal transition is originated from the structural change.
