Electronic and Transport Properties of Quasi-1D Wires of Biological Molecules — •Björn Oetzel^1,2, Lars Matthes^1,2, Falk Tandetzky^1,2, Frank Ortmann^1,2, Friedhelm Bechstedt^1,2, and Karsten Hannewald^1,2 — ¹Institut für Festkörpertheorie und -optik, Friedrich-Schiller-Universität Jena, Max-Wien-Platz 1, 07743 Jena — ²European Theoretical Spectroscopy Facility, Friedrich-Schiller-Universität Jena, Max-Wien-Platz 1, 07743 Jena

In the search for organic materials with good charge-transport properties, artificial stacks of biological molecules are considered attractive candidates [1,2]. In this spirit, we present ab-initio DFT calculations of the structural, electronic, and quantum-transport properties of quasi-1D wires based on guanine and eumelanin molecules [3]. Hereby, a special focus is put on the results for the electronic bandwidths and the consequences for potential applications.
