Abstract
Electronic properties of multidefected zigzag singlewalled carbon nanotubes are investigated by use of the tightbinding Green’s function method The StoneWales defects and the vacancies are considered We find that the conductance sensitively depends on the realistic defect configurations for the metallic zigzag carbon nanotubes Interestingly the electronic transport properties of the nanotubes with three vacancies can be considered as the sum effect of two doublevacancies while those with StoneWales defects can not The electron interference along the longitudinal axis and the transport blocking are observed which may be useful for understanding the electron transport behavior of carbon nanotube in experiments
