Phys. Rev. Lett. 98, 166805 (2007) [4 pages]Elucidation of the Electronic Structure of Semiconducting Single-Walled Carbon Nanotubes by Electroabsorption SpectroscopyReceived 23 January 2007; published 20 April 2007 We report benchmark calculations of electroabsorption in semiconducting single-walled carbon nanotubes that provide motivation to perform electroabsorption measurement on these systems. We show that electroabsorption can detect the continuum bands in different energy manifolds. Direct determination of the binding energies of excitons in higher manifolds thereby becomes possible. We also find that electroabsorption can provide evidence for Fano-type coupling between the second exciton and the lowest continuum band states. © 2007 The American Physical Society URL:
