Chirality cnt
Optical absorption in carbon nanotubes differs from absorption in conventional 3D materials by presence of sharp peaks (1D nanotubes) instead of an absorption threshold followed by an absorption increase (most 3D solids). Absorption in nanotubes originates from electronic transitions from the v2 to c2 (energy E22) or v1 to c1 (E11) levels, etc. The transitions are relatively sharp … WebThe chirality (or chiral vector) is very important because it determines the electronic properties of a CNT. CNTs can be classified into semiconducting and metallic depending …
