Abstract
The conditions for inhomogeneous electrical conduction to occur in liquid semiconductors is discussed. It is concluded from thermodynamic evidence that these conditions probably occur in the Tl-Te system. For the other systems considered (As-Te, In-Te, In-S) there is insufficient thermodynamic data, but it is suggested that conditions are probably similar to those in the Tl-Te system. The inhomogeneous cluster model is applied to all four systems, and a very good fit to the experimental data is found. In the In-Te system it appears that two different types of semiconducting cluster can exist, corresponding to the two congruently melting compounds.
