Interaction of Plasmas with Ceramic Materials — •Thomas Strunskus and Franz Faupel — Institute of Materials Science - Multicomponent Materials, Christian-Albrechts University at Kiel, Kaiserstr. 2, 24143 Kiel, Germany

In this project, the interaction of different plasmas with ceramic materials (mainly tin dioxide, titanium dioxide and aluminum oxide) will be investigated. The goal is to gain fundamental insight how the plasma exactly modifies a ceramic material on and also below the surface. In recent years plasmas have been frequently used to modify oxide materials but the approach was mainly empirical just identifying the induced change of properties (e.g., change in conductance, sensoric or optical properties). Little attention has been given to the exact mechanisms of these modifications. Here, starting with identifying the relevant species in the plasma and their transport to the surface we will correlate the plasma properties with the modifications induced at the ceramic surface identified with surface analytical techniques. The investigation will also include aging of the plasma modified surfaces. Samples range from single crystals, over multicrystalline thin films to nanostructures (nanowires and nanoparticles) of the same material.
