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
TLDR
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.
TLDR
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.

Efficient narrow-band light emission from a single carbon nanotube p-n diode.
TLDR
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.

Extremely Efficient Multiple Electron-Hole Pair Generation in Carbon Nanotube Photodiodes
TLDR
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.

Field-modulated carrier transport in carbon nanotube transistors.
TLDR
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.

TLDR
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.
