Strain and composition dependencies of the near bandgap optical transitions in monoclinic (Al${}_x$Ga${}_{1-x}$)${}_2$O${}_3$ alloys with coherent biaxial in-plane strain on (010) Ga${}_2$O${}_3$

The bowing of the energy of the three lowest band-to-band transitions in $\beta$-(Al${}_x$Ga${}_{1-x}$)${}_2$O${}_3$ alloys was resolved using a combined density functional theory (DFT) and…
