Spectral measurement of the breakdown limit of $\beta -G{a}_2{O}_3$ and tunnel ionization of self-trapped excitons and holes

Md M. Adnan, Darpan Verma, Zhanbo Xia +3

$\beta -G{a}_2{O}_3$ is an unusual semiconductor where large electric fields (~1-6 MV/cm) can be applied while still maintaining a dominant excitonic absorption peak below its ultra-wid…
