Abstract: According to the fundamental concept of mesoscopic physics, semi-classical electronic transport theory and the electronic structure of carbon nanotube, the conductance property of undoping metallic single-wall carbon nanotubes(SWNTs) was studied theoretically. Calculations show that the conductance of SWNT is quantized.

Key words: carbon nanotubes, electronic structure, conductance property
