Quantification of the strong, phonon-induced Urbach tails in \b{eta}-Ga2O3 and their implications on electrical breakdown
Ariful Islam, Nathan David Rock, Michael A. Scarpulla
In ultrawide bandgap (UWBG) nitride and oxide semiconductors, increased bandgap (Eg) correlates with greater ionicity and strong electron-phonon coupling. This limits mobility thro…

Utilizing (Al, Ga)2O3/Ga2O3 superlattices to measure cation vacancy diffusion and vacancy-concentration-dependent diffusion of Al, Sn, and Fe in \b{eta} -Ga2O3
Nathan D. Rock, Haobo Yang, Brian Eisner +9
Diffusion of native defects such as vacancies and their interactions with impurities are fundamental in semiconductor crystal growth, device processing, and long-term aging of equi…
