| Outline of Final Research Achievements |
Two-dimensional graphene nanoribbons networks were fabricated from organic synthesized Z-bar linkage precursor molecules using our developed two-zone chemical vapor deposition technique. Two-dimensional graphene nanoribbons networks consist of fused wider GNR structures and ladder type structure via a C-C bond formation of adjacent GNRs. Upon a transition from the one-dimensional GNRs to two-dimensional graphene nanoribbons networks by an annealing, the electrical conductivities and carrier mobilities enhanced more than 5 orders magnitude. Additionally, 2D structures showed the significantly small thermal conductivities regarded as one of the most lowest values from carbon based materials.
