Lieber. 2002. “One-Dimensional Energy Dispersion of Single-Walled Carbon Nanotubes by Resonant Electron Scattering.” Physical Review Letters 88 (6). https://doi.org/10.1103/physrevlett.88.066804.0031-90071079-71141092-0145http://nrs.harvard.edu/urn-3:HUL.InstRepos:41417283We characterized the energy band dispersion near the Fermi level in single-walled carbon nanotubes using low-temperature scanning tunneling microscopy. Analysis of energy-dependent standing wave oscillations, which result from quantum interference of electrons resonantly scattered by defects, yields a linear energy dispersion near E-F, and indicates the importance of parity in scattering for armchair single-walled carbon nanotubes. Additionally, these data provide values of the tight-binding overlap integral and Fermi wave vector, in good agreement with previous work, but indicate that the electron coherence length is substantially shortened.en-USJournal Article2019-09-2710.1103/PhysRevLett.88.066804
