Abstract

Thin AlN films were grown by molecular beam epitaxy on MgO(001) substrate with a thin TiN buffer layer. The as-prepared AlN/TiN/MgO(001) interfaces have been characterized by cross-sectional high-resolution electron microscopy (HREM). It is found that the thin TiN buffer layer is epitaxially grown on the MgO(001) substrate and hexagonal AlN epitaxially on the as-received TiN(001). Based on the growth orientation relationship and HREM images, atomistic structure models for the AlN/TiN interface are proposed, image simulated, and compared with experimental images.
