Polymers and polymer metal composite thin films prepared by pulsed laser deposition — •Thorsten Scharf, Erik Süske, Jörg Faupel, and Hans-Ulrich Krebs — Institut für Materialphysik, Universität Göttingen, Tammannstrasse 1, 37077 Göttingen

On the way to materials for new applications thin films play an important role. Pulsed laser deposition (PLD) is a very flexible method to deposit thin films out of many materials. The possibility to deposit polymers and metals in a one-step-process in ultra high vacuum raises the possibility to achieve new material classes.

Polymer (PMMA, PC) and polymer-metal (Cu,Ag,Au,…)-composites were laser-deposited under different parameters. Depending on the used polymer and metal there are different solubilities of metals in polymers. For lower metal concentrations the metal is solved in the polymer, but changes its material properties. Above this limit the metals form clusters already during the deposition process. The size-distribution and abundance of clusters also strongly depends on the used materials. The process of film growth and its impact on the properties will be discussed.
