Terahertz transitions in carbon nanotubes and graphene nanoribbons

Terahertz transitions in carbon nanotubes and graphene nanoribbons

Interband dipole transitions are calculated in quasi-metallic single-walled carbon nan-otubes and armchair graphene nanoribbons. It is shown that the curvature effects for tubes and the edge effects for ribbons result not only in a small band gap opening, corresponding to THz frequencies, but also i...
