“…They are induced by a gain in kinetic energy due to the formation of Clar's sextets in the bulk of graphene, which only become possible, if uncompensated π‐electrons are placed at any third edge atom of the zig‐zag edge, eventually forming the edge state . Experimental evidence for such edge states has indeed been found for graphene edges on different substrates such as HOPG , Si(100) , Au(111) , Cu(001), if the graphene is laterally interfaced with BN, , arguably Pt(111) , SiC(0001) , and SiO 2 . Spectroscopic features at the step edges of Ir(111) covered with graphene have also been interpreted in terms of graphene edge states , albeit it is known that the graphene layer is not interrupted at the Ir step edges .…”
