Developing an Analysis Procedure and Dispersion Model for Pristine and W-Doped VO₂ Thin Films Using Density Functional Theory and Spectroscopic Ellipsometry.

ABSTRACT: Vanadium dioxide (VO₂) and its unique phase transition from semiconductor to metal near room temperature (T_IMT = 68 °C) offer significant potential for applications in smart materials and advanced technologies. This transition is accompanied by a drastic modulation of VO₂'s optical properties in the near- and far-infrared regions. Tungsten (W) has been successfully used as a dopant to lower the transition to room temperature. VO₂ is highly dependent on the synthesis method, as for each fabrication protocol, the optical properties differ. Therefore, the optical properties of VO₂ must be determined frequently. In this work, a universal analysis procedure to accurately determine the optical properties of all pristine VO₂
