Electronic and Transport Properties of Quasi-1D Wires of Biological Molecules — •Björn Oetzel1,2, Lars Matthes1,2, Falk Tandetzky1,2, Frank Ortmann1,2, Friedhelm Bechstedt1,2, and Karsten Hannewald1,21Institut 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.
