摘要: A magnetic field is found to have strong effects on the electronic structure and bulk properties of carbon nanotubes. field-induced metal-insulator transition predicted for all pure In a weak field, nanotubes exhibit both large diamagnetic paramagnetic responses depending direction, Fermi energy, helicity, nanotube radius. Universal scalings are in susceptibility as functions temperature, size Comparison with recent experiments discussed.
