Abstract: Polarity dependence of the crystal growth rate, evaporation rate and chemical etching behavior of ZnO, CdS and ZnS crystals was investigated. After chemical etching the plus polar surfaces of these crystals show a few pits on them, whereas the minus polar surfaces are deeply etched and become rough. The preferential growth direction of ZnO in the polar direction is the plus polar direction and that of CdS and ZnS is the minus one. In addition, the evaporation rate is larger on the plus polar surface than on the minus one in ZnO and it is larger on the minus polar surface in CdS and ZnS. These results show that the surface energy of the plus polar surface is larger than that of the minus one in ZnO, but the relation reverses in CdS and ZnS.
