    Bright infrared emission from electrically induced excitons in carbon nanotubes (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-11-19
    Description: We used the high local electric fields at the junction between the suspended and supported parts of a single carbon nanotube molecule to produce unusually bright infrared emission under unipolar operation. Carriers were accelerated by band-bending at the suspension interface, and they created excitons that radiatively recombined. This excitation mechanism is approximately 1000 times more efficient than recombination of independently injected electrons and holes, and it results from weak electron-phonon scattering and strong electron-hole binding caused by one-dimensional confinement. The ensuing high excitation density allows us to observe emission from higher excited states not seen by photoexcitation. The excitation mechanism of these states was analyzed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Jia -- Perebeinos, Vasili -- Freitag, Marcus -- Tsang, James -- Fu, Qiang -- Liu, Jie -- Avouris, Phaedon -- New York, N.Y. -- Science. 2005 Nov 18;310(5751):1171-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉IBM Research Division, Thomas J.
