Tailoring light holes in ${\hat{I}}^2$-$G{a}_2{O}_3$ via Anion-Anion Antibonding Coupling

Ke Xu, Qiaolin Yang, Wenhao Liu +3

A significant limitation of wide-bandgap materials is their low hole mobility related to localized holes with heavy effective masses ($m_h^{\ast }$). We identify in low-symmetric wide-ba…
