Evidence for graphene edges beyond zigzag and armchair
The edges of nanoscopic objects determine most of their properties. For this reason the edges of honeycomb carbon---always considered either zigzag- or armchairlike---need special attention. In this Brief Report we provide experimental evidence confirming a previous unexpected prediction: zigzag is a metastable edge as its planar reconstruction lowers energy and …
