The metal-insulator transition in disordered tungsten bronzes. Results of an Anderson-Mott-Hubbard model
- Abstract:
-
To understand the electronic properties - in particular the metal -insulator transition (MIT) - of cubic tungsten bronzes NaxWO3 and NaxTayW1-yO3, a microscopic model incorporating electron interactions and correlated disorder is presented and treated at the mean-field level of unrestricted Hartree-Fock. The conduction band is found to exhibit a pseudogap at the Fermi level for sufficiently large interaction strengths, in agreement with experiment. The pseudogap has a profound effect on local...
