Abstract

Abstract Growth characteristics and optical properties of ZnO films epitaxially grown on Al2O3 (0 0 0 1) substrates at temperatures of Tg=200–500 °C by metalorganic chemical vapor deposition were investigated. The in-plane orientation of ZnO unit cells was different for Tg=200 °C and Tg⩾300 °C. The surface morphology varied significantly: smooth surface with cracks at Tg⩽250 °C, facet and column growth at 300 °C⩽Tg
