Abstract

The characterisation of vanadium dioxide (VO₂) conductivity has proved to be difficult due to varying properties of stoichiometry, grain size, and crystallinity from the different deposition techniques. We present a new waveguide technique based on time-resolved microwave conductivity (TRMC) technique to characterize VO₂ conductivity and material parameters. We show that TRMC is an adaptable technique for obtaining the electromagnetic material properties of VO₂ compounds as well as the conductivity. We have also made further progress on VO₂ deposition technique and films grown have better stoichiometry than previously reported literature. Recently we also did Tungsten incorporated VO₂ as well for low temperature transition.
