Calculation of polarizability tensor for different types of single-wall carbon nanotubes

Optical properties of open-ended armchair single-wall carbon nanotubes (SW-CNT) are studied by numerical simulations. The polarizability tenzor as main identifier of properties was analysed for different types of SW-CNT with various lengths. It is revealed that increase in nanotube length cause an increasing of polarizability degree that leads to essential change of SW-CNT optical properties.
