Formation of polycrystalline and microcrystalline composite thin films by codeposition and surface chemical reaction

The formation mechanisms of nanocrystalline composite structures are discussed, and results on co-deposited material system of C-60-Au, C-60-Cu as well as Al-SiOx are presented. Three type of structures are distinguished in the composite films, depending on the concentration of the additive. The decisive structure-forming phenomena are the kinetic segregation of the minority species and the chemical reaction of the deposited components. (C) 2000 Published by Elsevier Science S.A.
