摘要：
The electroluminescence from single-walled carbon nanotube field effect transistors is spectrally resolved, and shows two distinct modes of light emission. The vast majority of nanotubes have spectrally broad emission consistent with the spectrum of blackbody radiation. Much more rarely, superposed on the broad emission is a single narrow (<50 meV) peak which is consistent with expectation for electron-hole recombination. The narrow emission is strong even at lower biases and in general has greater peak intensity than the broadband emission. (c) 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
