Computational identification of Ga-vacancy related electron paramagnetic resonance centers in $\beta$-Ga${}_2$O${}_3$

Dmitry Skachkov, Walter R. L. Lambrecht, Hans Jürgen von Bardeleben +3

A combined experimental/theoretical study of the EPR in irradiated $\beta$-Ga${}_2$O${}_3$ is presented. Four EPR spectra, two $S=1/2$ and two $S=1$, are observed after high-energy proton…
