The structure and orientation of crystals in deposits of metals on mica
Abstract
Thin films of gold, palladium, and nickel, have been deposited in ultra-high vacuum on to mica freshly cleaved in vacuum. Electron microscopy was used to study the structure and orientation of films of various thicknesses deposited at substrate temperatures between 100 and 500°C. In the early stages of growth, the films consisted of small crystals which were frequently multiply-twinned and multiply-positioned. The growth of these crystals from nuclei is discussed and related to the high incidence of twinning. The final continuous films of nickel and palladium were {111} single crystals, but with different orientations with respect to the mica. Gold formed a polycrystalline film with a [111] texture.
