Silver was epitaxially deposited onto single crystal films of iron oriented with (001) parallel to their planes at various substrate temperatures between 100 and 700°C. Initial deposits of silver formed isolated three-dimensional nuclei at all temperatures investigated. The orientation relationship between the silver and iron was (001)-silver parallel to (001)-iron and [100]-silver parallel to [110]-iron. When the substrate temperature was relatively low (∼100°C), the silver deposits form a nearly continuous overlayer at an average thickness of about 150 A and the misfit between the silver and iron was accommodated partly by misfit dislocations arranged along the [110]-silver directions. At higher substrate temperatures, the orientation of the misfit dislocations became parallel to the [100]-silver directions. The Burgers vectors of the misfit dislocations were of the a/2[011]-silver type and inclined at 45° to the silver-iron interface. The nature of the interface dislocations changed from a mixed type to a pure edge type with increasing substrate temperature.
