Polarized infrared optical emission was observed from a carbon nanotube ambipolar field-effect transistor (FET). An effective forward-biased p-n junction, without chemical dopants, was created in the nanotube by appropriately biasing the nanotube device. Electrical measurements show that the observed optical emission originates from radiative recombination of electrons and holes that are simultaneously injected into the undoped nanotube. These observations are consistent with a nanotube FET… 
Bright Infrared Emission from Electrically Induced Excitons in Carbon Nanotubes
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 allows us to observe emission from higher excited states not seen by photoexcitation.
The polarized carbon nanotube thin film LED.
It is found that the threshold-less light generation efficiency in the intrinsic carbon nanotube film segment can be enhanced by increasing the potential drop across the junction, demonstrating the LED-principle in a carbon nanOTube film for the first time.
IR emission from Schottky barrier carbon nanotube FETs
Single-walled carbon nanotubes (SWNTs) are tubular 1D nanostructures made of /spl pi/ conjugated C-C bonds. The nanotube band structure consists of unique sets of 1D subbands resulting in sharp peaks

Carrier transport and light-spot movement in carbon-nanotube infrared emitters
Infrared emission from a carbon-nanotube (CNT) field-effect transistor, with the position of the light spot controlled by applied bias, was recently reported. In this letter, a self-consistent
Efficient narrow-band light emission from a single carbon nanotube p-n diode.
A new level of control over electrical carrier injection is achieved, reducing power dissipation by a factor of up to 1,000, and resulting in zero threshold current, negligible self-heating and high carrier-to-photon conversion efficiencies.
A quantum model for light emission performance of carbon nanotube field effect transistor
We propose a full quantum model based on non-equilibrium Green function method to simulate short channel, ohmic-carbon nanotube field effect transistor as light emitter. We consider carrier
Extremely Efficient Multiple Electron-Hole Pair Generation in Carbon Nanotube Photodiodes
Spatially and spectrally resolved photocurrent combined with temperature-dependent studies suggest that these steps result from efficient generation of multiple electron-hole pairs from a single hot E22 carrier, which is both of fundamental interest and relevant for applications in future ultra-efficient photovoltaic devices.

We use scanning gate microscopy to precisely locate the gating response in field-effect transistors (FETs) made from semiconducting single-wall carbon nanotubes. A dramatic increase in transport
Field-modulated carrier transport in carbon nanotube transistors.
The experiments show that the bulk properties of the semiconducting carbon nanotubes do not limit the current flow through the metal/nanotube/metal system and can be understood in the framework of gate and source-drain field induced modulation of the nanotube band structure at the source contact.
Ambipolar electrical transport in semiconducting single-wall carbon nanotubes.
Single-wall carbon nanotube (SWNT) field-effect transistors offer the novel possibility of ambipolar Ohmic contacts and the properties of SWNT junctions to TiC are discussed in detail.
Band Gap Fluorescence from Individual Single-Walled Carbon Nanotubes
At pH less than 5, the absorption and emission spectra of individual nanotubes show evidence of band gap–selective protonation of the side walls of the tube, which is readily reversed by treatment with base or ultraviolet light.
