Research Abstract |
The electronic structure of nanographene crucially depends on the edge geometry. This is a consequence of the boundary condition of the massless Dirac fermion in physics, while it can be understood on the basis of aromaticity in chemistry. We investigated the role of edge geometry in the electronic structure using STM/STS, AFM, Raman scattering, NEXAFS and magnetic and transport investigations. It is found that nonbonding edge state, which is sensitive to edge chemistry details, is created in the zigzag edges, while electron wave interference contributing to the electronic stability takes place in the armchair edges.
