Intra- and Inter-Conduction Band Optical Absorption Processes in $\beta$-Ga${}_2$O${}_3$

Arjan Singh, Okan Koksal, Nicholas Tanen +6

$\beta$-Ga${}_2$O${}_3$ is an ultra-wide bandgap semiconductor and is thus expected to be optically transparent to light of sub-bandgap wavelengths well into the ultraviolet. Contrary to t…
