   Abstract:
   The evaporation and solution morphologies of ZnO single crystals have been investigated. In the case of solution etching, using HCl, the {00.1} surface develops etch pits with sharp rims while for the {00.1¯} surface, etch-pit rims are unstable. Similar effects are found for evaporation near 1035°C. As the evaporation temperature is increased to near 1200°C, however, the {00.1¯} surface becomes increasingly complex before assuming a more stable habit at still higher temperatures. Both {10.2¯} and {11.2¯} planes are developed on the {00.1¯} surface, but the corresponding planes on the {00.1} surface are not observed
