The Sublimation of Basal Surfaces of Zinc Oxide.
Abstract
Basal surfaces of both undoped and lithium-doped single crystals of zinc oxide were sublimated under Langmuir free vaporization conditions and under various partial pressures of oxygen. The vaporization coefficient was lower for the (0,0,0,-1) surface than for the (0001) surface. Oxygen suppressed the sublimation rates except for the (0001) surface at high temperatures. Lithium doping produced a large increase in sublimation rates. An earlier theory of surface-charge influenced sublimation was modified to include specific effects of surface kinks, surface roughening, and doping. The experimental results could be interpreted in terms of this modified theory.
