| Research Abstract |
Porous structure of double-layer graphene was proposed as a model system for the multilayer graphene with fused edges that had been realized by heat-treatment experiments and a structure-generating algorithm was devised. The nanoporous structure is generated by removing carbon atoms within a region on both top and bottom graphene layers and then periodically arranging the nanopores thus generated. Around the juncture of nanopores one needs 12 heptagons for each. The π-electronic states of smaller nanoporous double-layer graphene depends on the arrangement of nanopores and heptagons. The π-electronic states of larger ones is, however, metallic irrespective of structure and exhibits special states near the Fermi level that are localized to the nanopore region
