Effective Phonon Dispersion of $\beta$- (Al${}_x$Ga${}_{1-x}$)${}_2$O${}_3$ alloy semiconductor

Ankit Sharma, Animesh Datta, Uttam Singisetti

In this work, the Effective Phonon Dispersion of $\beta$- (Al${}_x$Ga${}_{1-x}$)${}_2$O${}_3$ alloy is investigated using the Phonon unfolding formalism. To capture the true randomness of the…
