Abstract
Theoretical and experimental results on film/substrate interface energ etics and misfit accommodation in Pt thin films on (001) MgO are repor ted. Two epitaxial orientations were observed in Pt films deposited on to (001) MgO substrates by electron beam evaporation: [110](001)Pt//[ 110](001) MgO and [110](111)Pt//[110](001) MgO. O-lattice calculations were used to predict film/substrate interface structures and relative interfacial energies for these two epitaxial Pt film orientations. Th e interfacial misfit dislocation structure was characterized by weak b eam transmission electron microscopy. Good agreement was found among t he calculated relative interface energies, reports in the literature, and the present experimental data. Copyright (C) 1997 Acta Metallurgic a Inc.
