Abstract

Magnetoconductance of carbon nanotubes (CNTs) is investigated. We clearly show that a semiconducting CNT can be converted into a metallic one, or vice versa, with the application of a large magnetic field parallel to the tube axis, providing a consistent confirmation of the Aharonov-Bohm (AB) effect on the band structure of CNTs. Wealso demonstrate that magnetic-field values where the ...
