Molar Volume and Compressibility of the Liquid Bi--Se System

Abstract

Density and sound velocity measurements have been made to investigate the thermodynamic properties of the liquid Bi--Se system. The molar volume and isothermal compressibility have been deduced as a function of composition which show large negative deviation from the ideal behaviour. The results suggest that Bi₂Se₃ assembly having a densely packed structure causes semimetallic nature of this system.
