Query: High Infrared Reflectance Modulation in VO2 Films Synthesized on Glass
  and ITO coated Glass substrates using Atmospheric Oxidation of Vanadium   Vanadium Dioxide (VO2) is a strongly correlated material, which exhibits
insulator to metal transition at ~68 C along with large resistivity and
infrared optical reflectance modulation. In this work, we use atmospheric
pressure thermal oxidation of Vanadium to synthesize VO2 films on glass and ITO
coated glass substrates. With the optimized short oxidation durations of 2 min
and 4 min, the synthesized VO2 film shows high optical reflectance switching in
long-wavelength infrared on glass substrates and mid-wavelength infrared on ITO
coated glass substrates, respectively. Peak reflectance switching values of
~76% and ~79% are obtained on the respective substrates, which are among the
highest reported values. Using the reflectance data, we extract VO2 complex
refractive index in infrared wavelengths, in both the insulating and metallic
phases. The extracted refractive index shows good agreement with VO2
synthesized using other methods. This demonstration of high optical reflectance
switching in VO2 thin films, grown on low cost glass and ITO coated glass
substrates, using a simple low thermal budget process will aid in enhancing VO2
applications in the optical domain.
