(Color online) (a) XRD patterns and (b) temperature dependent resistance R(T) curves for VO2 films grown on amorphous glass substrates. The oxygen pressure for the VO2 deposition varied from 1 mTorr to 15 mTorr. The inset shows the AFM image for the VO2 film made at 10 mTorr.
(Color online) Optical transmittance spectra for VO2 films made at (a) 1 mTorr, (b) 5 mTorr, and (c) 15 mTorr.
(Color online) (a) The optical absorption edge of VO2 films with the temperature and (b) the schematic band diagram of VO2. The schematic band diagram referred to the previous reports.22–25
(Color online) Temperature dependence of optical transmittance of VO2/glass samples measured at (a) 2500 nm and (b) 700 nm.
