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 C60–Au, C60–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.
