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 ...

Carbon nanotubes (CNTs) are cylindrical nanostructures formed by rolling a single layer of graphene into a seamless tube. The graphene sheet consists of carbon atoms arranged in a hexagonal lattice, ...

Atomic force microscopy (AFM) is a standard imaging technique for the structural characterization of surfaces in different fields of materials science, surface science, and biology. Carbon nanotubes ...
