Carbon Atomic Chains from Graphene
Optimized geometries of carbon atomic chains constrained by two GNRs with various types of edges. (a) a 8-sp-atom chain bridging two GNRs with 5-7 edges,(b) a 9-sp-atom chain bridging two GNRs with zigzag edges, (c) a 10-sp-atom chain bridging two GNRs with armchair edges, (d) a 12-sp-atom chain bridging two GNRs with armchair edges.
