Abstract

Optical absorption and photoconductivity have been observed in the ultraviolet in single crystals of nominally pure $\ensuremath{\beta}\ensuremath{-}{\mathrm{Ga}}_{2}{\mathrm{O}}_{3}$. At room temperature a steep absorption edge, characteristic of a band-to-band transition, is observed at 2700 \AA{}...
