Abstract

The heteroepitaxial growth of single-crystal rare earth oxide films on single-crystal gallium nitride (GaN) films was investigated. The epitaxial overgrowth of single crystal GaN films on the rare earth oxide films was also examined. A sixfold symmetry in the in-plane epitaxy was observed using reflection high-energy electron diffraction. The single-crystal oxide films were found to be the high temperature hexagonal phases of the sesquioxides. The crystallographic hexagonal close-packed (hcp) structures of both layers of GaN were also investigated.
