Broad-range multiphase EOS of a strong oxide to more than 1 TPa.
POSTER
Abstract
We present ongoing work on the design of a broad-range multiphase equation of state (EOS) of gallium
oxide. Ga2O3 is an important functional material with rich physicochemical properties and emerging
candidate for applications in different fields like high power electronics, optoelectronics and more. Many
of the standard EOS models currently in use are geared to simple elemental metals. Ga2O3 pushes the
modeling beyond the basic physics assumptions. The complex nature of the crystalline structures lends to
a directional dependency. These dependencies make various quantities like thermal expansion and the
compression response change according to crystalline orientation. We are currently modelling the EOS
for four of the solid phases and the liquid.
