Model for the Electronic Structure of Metal Tungsten Bronzes

摘要

The electronic properties of the metal tungsten bronzes of highxvalue are interpreted in terms of a model in which the conduction electron wavefunctions are derived principally from the metal atomicpfunctions. It is shown that the physical properties of the bronzes are consistent with this model, which is compared, in this respect, with others. The transition to metallic conductivity at lowxvalues is discussed, using the theory of Mott, and a number of experiments are suggested for clarifying some features of the electronic structure of the tungsten bronzes, and also of the related vanadium bronzes.
