Cross-Polarized Exciton Absorption in Semiconducting Carbon Nanotubes

Part of the Springer Proceedings in Physics book series (SPPHY, volume 119)


The Aharonov-Bohm effect on optical absorption of light polarized perpendicularly to the tube axis in semiconducting carbon nanotubes is studied. The excitation energy quadratically decreases with the flux around zero in contrast to the linear splitting for light polarized parallel to the axis.
