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.
} 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.} surface becomes increasingly complex before assuming a more stable habit at still higher temperatures. Both {10.
} and {11.} planes are developed on the {00.} surface, but the corresponding planes on the {00.1} surface are not observed. (The development of second order pyramidal planes is also observed in vapor grown needles from ore-processing furnaces).
