Bailey, S. W. and Tomanek, D. and Kwon, Y. K. and Lambert, C. J. (2002) Giant magneto-conductance in twisted carbon nanotubes. EPL, 59 (1). pp. 75-80. ISSN 0295-5075
Using the Landauer-Büttiker formalism, we calculate the effect of structural twist on electron transport in conducting carbon nanotubes. We demonstrate that even a localized region of twist scatters the propagating π electrons and induces the opening of a (pseudo-) gap near the Fermi level. The subsequent conductance reduction may be compensated by an applied axial magnetic field, leading to a twist-induced, giant positive magneto-conductance in clean armchair nanotubes.
