Energy Spectra of Triangular Multilayer Graphene Quantum Dots — •Julienne Scheller, Christian Wimmenauer, and Thomas Heinzel — Institute of Experimantal Condensed Matter Physics, Heinrich-Heine-University Düsseldorf
Triangular Multilayer Graphene Quantum Dots (GQDs) are modelled using a tight binding approach. The energy gaps are calculated as a function of disk radius, number of disk layers and edge type. Armchair edge type and zigzag edge type GQDs are investigated for up to 7 layers and in the limit of infinitely many layers. To further discuss the differences between both edge types the density of states and the ground state wavefunctions are calculated.
