Tight-Binding Simulation of Graphene Quantum Dots — •Christian Wimmenauer and Thomas Heinzel — Solid State Physics Laboratory (IPkM), Heinrich-Heine-Universität Düsseldorf

Graphene quantum dots (GQD) are simulated with an tight binding approach to obtain a better understanding of recent experimental findings regarding the electronic and optical properties of these nanoparticles. The emphasis lies on studying the influence of different edge structures, functional groups and defects on the fluorescence spectra. Using the KWANT software package, hexagonal zigzag edge type, as well as armchair edge type, GQDs have already been modeled. The results are supposed to be used to prepare GQDs with improved optical properties for biological applications.
