Phys. Rev. Lett. 94, 026801 (2005) [4 pages]Anomalous Conductance Quantization in Carbon NanotubesSee Also: Erratum Received 25 June 2004; published 18 January 2005 Conductance measurements of carbon nanotubes containing gated local depletion regions exhibit plateaus as a function of gate voltage, spaced by approximately 1e2/h, the quantum of conductance for a single (nondegenerate) mode. Plateau structure is investigated as a function of bias voltage, temperature, and magnetic field. We speculate on the origin of this surprising quantization, which appears to lack band and spin degeneracy. © 2005 The American Physical Society URL:
