Scientists developed carbon nanotube technology that can achieve radio frequency (RF) speeds in excess of 100 gigahertz (GHz), which would permit better military and commercial communications systems.

Carbon nanotube transistors push up against quantum uncertainty limits Five nanometer features, lower voltage, and a faster switching speed.

They're not the first transistors created using carbon nanotubes (CNTs), but researchers at the University of Wisconsin-Madison (UW-Madison) claim their new carbon nanotube transistors are the ...

Carbon nanotube transistors should be able to perform five times faster or use five times less energy than silicon transistors, according to extrapolations from single nanotube measurements.

The team's breakthrough could pave the way for carbon nanotube transistors to replace silicon transistors, and is particularly promising for wireless communications technologies. - See more. view more ...

IBM’s carbon nanotube results satisfy the contact requirement all the way up to the 1.8-nanometer node (four technology generations of manufacturing technology away), showing that the technology ...

Carbon nanotube transistor (image source) This new process chain results in carbon nanotube field effect transistor (FET) arrays at a density of 50 transistors per micrometer and with quasi ...

"Making carbon nanotube transistors that are better than silicon transistors is a big milestone," said one of the team, Michael Arnold, from the University of Wisconsin-Madison.

That left the gate. In the previous 1 nanometer device, the gate was made of a single carbon nanotube. Getting smaller than that is difficult but not impossible.

Ion gels have been used in carbon nanotube transistors before (Nano Lett. 2013, DOI: 10.1021/nl3038773). That previous work took advantage of the gels’ compatibility with printing-based ...

In the pursuit of smaller transistors, IBM Research found that carbon nanotubes outperform silicon on speed and power consumption, offering a possible way to maintain the pace of Moore's Law.

Science Advances – Quasi-ballistic carbon nanotube array transistors with current density exceeding Si and GaAs “This achievement has been a dream of nanotechnology for the last 20 years,” says Arnold ...
