What is a single walled carbon nanotube?

Single walled carbon nanotubes (SWCNTs) can be considered as a single long wrapped graphene sheet. Nanotubes generally have a length to diameter ratio of about 1000 and hence considered nearly one-dimensional structures. SWCNTs generally have a diameter close to 1 nm and are multiple thousand times longer in length.
