Abstract
Three-terminal devices with conduction channels formed by quasi-metallic carbon nanotubes (CNT) are shown to operate as nanotube-based field-effect transistors under strong magnetic fields. This spectacular effect results from the Aharonov-Bohm phenomena at the origin of a band gap opening in metallic nanotubes. The off-state conductance of the devices varies exponentially with the magnetic flux intensity. We extract the quasi-metallic CNT chirality from the temperature-dependent magnetoconductance measurements.
