Fully transparent thin-film transistors based on aligned carbon nanotube arrays and indium tin oxide electrodes.
Sunkook Kim,Sanghyun Ju,Ju Hee Back,Yi Xuan,Peide D. Ye,Moonsub Shim,David B. Janes,Saeed Mohammadi +7 more
TL;DR: The first demonstration of fully transparent TFTs based on well-aligned SWNTs arrays, with conduction from source to drain occurring through individual SW NTs, rather than through networks, could be attractive candidates for future flexible and/or transparent electronics.
Effects of oxygen on the electron transport properties of carbon nanotubes: Ultraviolet desorption and thermally induced processes
TL;DR: In this paper, the authors examined the electrical response of carbon nanotubes to UV exposure and thermal treatments and found that low intensity UV-induced conductivity change in individual single-walled carbon-nanotube transistors was mainly arising from oxygen desorption at the metal contacts rather than from nanotube or possible amorphous side products.

pH-dependent electron-transport properties of carbon nanotubes.
Ju Hee Back,Moonsub Shim +1 more
TL;DR: Carbon nanotube electrochemical transistors integrated with microfluidic channels are utilized to examine the effects of aqueous electrolyte solutions on the electron-transport properties of single isolated carbon nanotubes, indicating that protonation does not lead to hole doping.

Low-frequency noise in ambipolar carbon nanotube transistors.
TL;DR: Low-frequency noise measurements on individual single-walled carbon nanotube transistors exhibiting ambipolar characteristics have been carried out, finding that most devices exhibit significantly larger noise amplitude in the n-channel operation that has a distinct dependence on the threshold voltage.

Manifestation of Kohn Anomaly in 1/f Fluctuations in Metallic Carbon Nanotubes
TL;DR: The results suggest that the competition between zone-center and zone-boundary phonon scattering is the underlying origin of the large enhancement and resonance-like behavior of 1/f noise.
