Abstract

This paper presents a study of the structural, vibrational, elastic, electrical, power and transport properties of $\ensuremath{\beta}$-Ga${}_{2}$O${}_{3}$ using first-principles simulation tools. The authors find that high energy optical phonons of B${}_{u}$ character account for most of the scattering limiting the carrier mobility.
