Abstract

The magnetoresistance of carbon nanotubes was analyzed to demonstrate metal-insulator transition related to flux dependent density of states (DOS). An exact numerical computation of Kubo conductivity for noninteracting electrons of a weakly disordered nanotube coupled to two disorder-free nanotube leads was also performed. The diffusion coefficient of wave packets was determined by solving the time-dependent Schrodinger equation. Tuning of carbon nanotube from positive to negative magnetoresistance was found to depend on the location of chemical potential and orientation of the magnetic field.
