Native point defects and low $p$-doping efficiency in $M{g}_2(Si,Sn)$ solid solutions: A hybrid-density functional study

Byungki Ryu, Eun-Ae Choi, Sungjin Park +5

We perform hybrid-density functional calculations to investigate the charged defect formation energy of native point defects in $M{g}_{2}Si$, $M{g}_{2}Sn$, and their solid solutions. The…
