Abstract : The electrical conductivity σ, the thermoelectric power S and the sound velocity C have been measured for liquid Te-Se mixtures in a wide temperature and pressure range. Substantial changes in σ and S from semiconducting to metallic values are induced by a slight application of pressure. The region where such changes occur is determined on the concentration-temperature plane and in that region the prominent maxima in the temperature variations of compressibility appear. It is suggested that the observed semiconductor-to-metal transition is originated from the structural change.
