Vanadium dioxide thin films were fabricated by rapid thermal annealing vanadium thin films in oxygen atmosphere. The effects of annealing time on metal-insulator transition properties and temperature dependent reflectance near isosbestic point were studied. The results show that the resistance of vanadium dioxide thin film changes over 1 order of magnitude after RTA at 450℃ for 30s. There is a dip in the reflectance spectrum of vanadium dioxide thin film for plasmonic resonance absorption, the dip shifts to low wavelength as vanadium dioxide changes from insulator to metal.
Keywords:vanadium dioxide;phase transition;rapid thermal annealing
