摘要: Unified bandgap engineering, valid both for the armchair and zigzag graphene nanoribbons (GNRs), is enunciated. Using boundary condition appropriate K-K' points of Dirac cones, GNRs are shown to exhibit three distinct semiconducting states SC0, SC1, SC2 with complete absence metallic state. The experimental 7-AGNR 13-AGNR (A) found be in excellent agreement SC1 Similar associations pointed out other configurations. Both data theoretical results show effective mass inversely proportional GNR width. directly bandgap. indexing scheme connects chiral index carbon nanotubes (CNTs) that used by making edge corrections dangling bonds.
