摘要

Electronic band in graphene and metallic carbon nanotube shows linear dispersion, where electrons behaves as massless Dirac fermions with pseudo-spin structure. In this talk, I will present the optical response of Dirac electrons in graphene, as well as plasmonic property of metallic carbon nanotubes, revealed by Fourier transform infrared spectroscopy (FTIR) and scanning near-field optical microscopy (SNOM).
