摘要: We have applied a third nearest-neighbor tight binding model to investigate the optical properties of CNTs in terms radius, chirality and magnetic field. The spectrum depends strongly on radius infrared region contrast middle energy region. dependence E22/E11 from peak positions band structure is similar. In region, by applying field, splitting rates show well-expressed family behaviors.
