Effect of Shape on Electronic and Magnetic Properties of Graphene Nanoribbons (GNRs)

We have studied electronic and magnetic properties of grapheme nano-structures with different shapes. In particular, we have studied both zigzag and armchair graphene nanoribbons (GNR) of triangular shape using density functional method. We find electronic and magnetic properties of triangular structures are drastically different from their rectangular counterparts and our results suggest that, in addition to size effect, shape of the structure has a large impact on the underlying intrinsic electronic properties of GNRs. We will compare our results with available experiments.
