INFRARED REFLECTANCE SPECTRA OF THE SODIUM TUNGSTEN BRONZES - EVIDENCE FOR A SURFACE DEPLETION LAYER

Infrared reflectance spectra of (001) surfaces of the sodium tungsten bronzes NaxWO3 have been measured in air. Reflectance minima are found close to the highest bulk LO phonon frequency. Comparison with model calculations suggests that there is a depletion layer 10 AA thick on the bronze surface.
