Role of carbon and hydrogen in limiting $n$-type doping of monoclinic (Al${}_x$Ga${}_{1-x}$)${}_2$O${}_3$

Sai Mu, Mengen Wang, Joel B. Varley +3

We use hybrid density functional calculations to assess n-type doping in monoclinic (Al${}_x$Ga${}_{1-x}$)${}_2$O${}_3$ alloys. We focus on Si, the most promising donor dopant, and study t…
