Photoelectron spectromicroscopy study of metal–insulator transition in NaxWO3

We have investigated the validity of percolation model, which is quite often invoked to explain the metal–insulator transition in sodium tungsten bronzes, NaxWO3 by photoelectron spectromicroscopy. The spatially resolved direct spectromicroscopic probing on both the insulating and metallic phases of...
