Abstract

Epitaxial lithium tantalate (LiTaO3) thin films were grown on the hexagonal plane of sapphire substrates by metal organic chemical vapor deposition. Two crystallographic variants, related to each other by 180° rotation around the c axis, as well as non-180° domains were determined by transmission electron microscopy from cross-sectional samples of these films. A structural model for the non-180° domain is proposed and the possible formation mechanisms are discussed.
