Temperature and magnetic field dependent photoluminescence from carbon nanotubes
International Journal of Modern Physics B 21:8-9 (2007) 1180-1188
Abstract:
Photoluminescence as a function of temperature and magnetic field from single walled carbon nanotube solutions is described. This is modelled assuming that it is dominated by the small energy splitting between the dark and bright states of the singlet excitons which are found to be in the region of 1-5 meV for nanotubes of 0.8-1.2nm. The emission energies show a large red-shift due to the introduction of an Aharanov-Bohm phase by magnetic field along the tube axis and the luminescence intensity is strongly enhanced at low temperatures due to the mixing of the different valley states of the excitons. © World Scientific Publishing Company.Erratum: Stark magnetophonon resonances in Wannier-Stark localized InAs∕GaSb superlattices [Phys.
