Abstract

Single crystal niobium films were grown by Molecular Beam Epitaxy (MBE) on (0001)s sapphire substrates. Cross-sectional specimens with thickness of <20 nm were prepared so that the Nb/A1203 interface could be investigated by high resolutionelectron microscopy (HREM). The orientation relationship between the metal film and the ceramic substrate was verified by selected area diffraction: (111)Nb ║(0001)S and [110]Nb║[2110]S. The atomistic structure of the interface was identified by HREM.
