We examine the effects of acid etchants on the two polar faces of bulk ZnO using photoluminescence and reflectance spectroscopy, as well as changes in surface topography using atomic-force microscopy. Although the (0 0 0 Γ1) surface exhibits intense bound-exciton emission and strong free-exciton res
