Plasma based deposition of functional nanocomposites — •Franz Faupel — Institute of Materials Science - Multicomponent Materials, Christian-Albrechts University at Kiel, Kaiserstr. 2, 24143 Kiel

Nanocomposites combine favorable features of the constituents on the nanoscale to obtain new functionalities. The present talk is concerned with the plasma based deposition of nanocomposites consisting of metal nanoparticles in a dielectric organic or inorganic matrix and the resulting functional properties. Deposition techniques include magnetron co-sputtering of the matrix and metallic components and the combination of a gas phase aggregation cluster source with magnetron sputtering or plasma polymerization. These methods inter alia allows the incorporation of alloy clusters with well defined composition and tailored filling factor profiles. Computer simulations of the metal aggregation process will also be addressed. Examples of nanocomposites presented range from optical composites with tuned particle surface plasmon resonances for plasmonic applications and magnetic high frequency materials with cut-off frequencies above 1 GHz to antibacterial coatings which benefit from the large effective surface of nanoparticles and the increased chemical potential which both strongly enhance ion release.

Financial support by the DFG within the Collaborative Research Center TR24 "Fundamentals of Complex Plasmas" is acknowledged.
