Mechanism of growth of ZnO single crystals from hydrothermal alkali solutions

AbstractThe results obtained in experiments on the growth of zinc oxide, ZnO, under hydrothermal conditions are generalized. The polar growth and nonstoichiometry of ZnO crystals are analyzed in terms of crystal chemistry with due regard for the physicochemical conditions of the growth medium. The effect of the Li+ and of di-and trivalent metal (Co2+, Fe2+, Mn2+, Fe3+, Mn3+, Sc3+, In3+) impurities on the kinetics and some physical characteristics of ZnO crystals are studied, and the chemical reactions occurring on the surfaces of the (0001) and $$(000\bar 1)$$ faces are considered.
