Abstract

Al and Sn were deposited simultaneously by applying two W evaporation sources. The structural evolution of codeposited layers was studied on amorphous (amorphous C films and oxidized Si wafers) and single-crystal (air-cleaved NaCl and mica) substrates at a temperature of 200 C and at various oxygen partial pressures. The codeposition of Sn enhances the self-surface diffusion of Al as well as the liquid-like coalescence of Al crystals, and decreases the sensitivity of structure evolution againts O2 Sn is segregated during the growth of Al crystals and forms three-dimensional particles. In O2 atmosphere a solid phase layer develops on the surface of growing Al crystals and the deposition proceeds by the formation of a line-grained. "cermet" like structure.
