Elastic stability of Ga${}_2$O${}_3$: Addressing the $\beta$ to $\alpha$ phase transition from first principles

Konstantin Lion, Pasquale Pavone, Claudia Draxl

Elastic and structural properties of $\beta$-Ga${}_2$O${}_3$ and $\alpha$-Ga${}_2$O${}_3$ are investigated from first principles. The full elastic tensors and elastic moduli of both phases at $0$ K…
