Nanostructures from electron beam assisted decomposition of gold nitrates — •Daniel Zink, Torsten Henning, and Peter J. Klar — Justus-Liebig-Universität Gießen, I. Physikalisches Institut, Heinrich-Buff-Ring 16, 35392 Gießen

To produce elemental gold in defined structures on substrates is of interest for a wide range of applications. It may be useful for optical and electrical devices, plasmonic structures or gold nanoparticles. The electron beam assisted decomposition of (NO₂)[Au(NO₃)₄] and (NO)[Au(NO₃)₄] has advantages compared with common methods for depositing gold nanostructures (including MOCVD or organic resists as PMMA) such as avoiding carbon contamination. The decomposition of gold precursor takes place by interaction with the electron beam. As in conventional e-beam lithography proximity effects need to be controlled in order to optimize the lateral resolution. We will present some first experiments using this novel method.
