“…The recent theoretical studies of graphene nanomeshes [7,10,11,[14][15][16][17][20][21][22] and, in particular, the advances in experimental preparation of such systems [9,12,13,16,18,19] clearly suggest the need for further detailed investigations, in order to elucidate the structures with highest application potential. In this context, we study the magnetic and electronic structure of a dense regular array of pores in graphene, each of the pores being passivated by nitrogen, and doped with a 3d transition metal atom.…”
