Structured hetero-material nanorod arrays — •Eric Jehnes, Vera Hoffmann, Fabian Patrovsky, Matthias Böhm, and Lukas M. Eng — Institute of Applied Photophysics, TU Dresden, D-01062 Dresden, Germany

Metal nanorod arrays grown in anodic aluminium oxide (AAO) show distinct plasmonic resonances [1] that cover a wide range of future applications - for instance in optical sensors, biosensors, nanoantennas, waveguides, etc.. In order to improve their applicability addional structuring is needed both laterally, horizontally and radially.

We show such an approach by laser interference lithography, electrochemical deposition and multiple etching steps. Our processing results in core-shell and segmented nanorods composed of gold, silver, cobalt and/or nickel. The lateral structuring creates nanorod arrangements of dense lines covering a large area.
