Carbon Nanotubes

Carbon nanotubes (CNTs) are a one-dimensional form of carbon. They are created when single layer hexagonal carbon lattices, similar to graphene, are rolled up to form elongated hollow tubes. These nanotubes can either be single walled (SWCNTs) or can have two (double-walled carbon nanotubes, or DWCNTs) or more tubes (mutli-walled carbon nanotubes, or MWCNTs) nested within one another. The dimensional constraints placed upon the carbon structure result in unique properties not found within bulk carbon.
