Abstract
The model of liquid semiconductors proposed by Enderby and Barnes (1990) is reviewed in the light of new experimental work and theoretical analysis. Particular attention is focussed on liquid silver chalcogenides which have been intensively studied over the past few years. It is concluded that at stoichiometry, the mobility remains finite and that the reduced conductivity arises from charge transfer. Thus the Anderson and related transitions are not significant so far as stoichiometric liquid semiconductors are concerned. The electronic properties are driven by chemical effects and suggest that the Mott-Hubbard model may be the most appropriate starting point for a complete theory.
