Description

Vanadium Dioxide (VO2) is a polycrystalline material that exhibits a reversible transition from a monoclinic semiconducting phase to a tetragonal metallic phase in the temperature range of 55 – 68 °C. The refractive index of VO2 also undergoes a dramatic change during this phase transition. In this project, the VO2 thin films were grown by ion-assisted deposition (IAD) using E-beam evaporation on sapphire substrates. A simulation model was developed to extract the optical constants from the measured reflectance and transmittance spectrum.
