Finding different materials to keep electronic devices evolving is a matter of scientists. A thermal electronic logic circuit (TELC) is one of the most prominent alternatives that has been proposed recently. Vanadium dioxide (VO2) is an essential material that has been utilised in TELC due to its thermal and electrical properties. VO2 transits its electrical property from the semiconductor phase into the metal phase at around 67oC. In this paper, two numerical methods were used to determine the electrical and thermal characteristics of VO2, and measured data compared the results.
