Component effects on the vanadium oxide thin films phase transition character phenomenon observed

We present what is, to the best of our knowledge, how the components affect the phase transition character of the vanadium oxide thin films. The vanadium oxide thin films are prepared on zinc selenide by a DC magnet sputtering method for the first time; the components are achieved by the x-ray photoelectron spectroscopy (XPS). The films are annealed to tune their components. A spectral transmittance study has been made from 2.5 to 25.0 μm. We can see that, except for doping, different components can change the phase transition characters of the films. The components can affect the phase transition temperature, hysteresis cycle, and the transmittance.
