Functionalization of oxide and oxide-metallic nanowire arrays — •Anshuma Pathak^1,2, Hongdan Yan¹, Johannes Dühn¹, Mehmet Fatih Cetin¹, Meinhard Schilling³, Marc Tornow², and Peter Lemmens¹ — ¹IPKM, TU-BS, Braunschweig, Germany — ²IHT, TU-BS, Braunschweig, Germany — ³EMG, TU-BS, Braunschweig, Germany

We investigate the functionalization of single crystalline, nanocrystalline and nanoporous Al₂O₃ surfaces as a coupling enabler to different molecular species. Our aim is to establish nanostructured, composite oxide-molecular materials that can be used as model systems for optically induced energy transfer. Nanoporous oxides are prepared using electrochemical oxidation leading to a dense array of pores. The pore walls are functionalized and in a subsequent step filled by Au wires using electrochemical deposition techniques. The characteristic length scales of the arrays are 20-30 nm with respect to diameter and distance of the pores. Specifically, we investigate the impact of different organic monolayer coatings to the pore walls on the growth and morphology of the Au nanowires.
