Fig. 3. (Color online) O K-edge x-ray absorption spectra of the as-grown MoO2 thin film and reductively annealed films at different temperatures. The x-ray absorption data were taken at (a) 300 K and (b) 80 K. The data clearly shows the evolution of pre-edge spectra near 530 eV. Note that complete removal of O K-edge is consistently seen from the reductively annealed MoO2 film at 1000 °C.
