Due to reaching the end of Moore’s era and minimising CMOS technology becomes difficult.
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. The phase-change
material behaviour was modelled by two different softwares using different simulation
methods, finite volume method FVM and finite element method FEM. The sample preparation
and the thermal and electrical measurements were carried out in our cleanroom.
