The researchers created the tiny transistor by simultaneously applying a force and low voltage which heated a carbon nanotube made up of few layers until outer tube shells separate, leaving just a single-layer nanotube.
The heat and strain then changed the "chilarity" of the nanotube, meaning the pattern in which the carbon atoms joined together to form the single-atomic layer of the nanotube wall was rearranged.
The result of the new structure connecting the carbon atoms was that the nanotube was transformed into a transistor.
Professor Golberg's team members from the National University of Science and Technology in Moscow created a theory explaining the changes in the atomic structure and properties observed in the transistor.
Lead author Dr. Dai-Ming Tang, from the International Center for Materials Nanoarchitectonics in Japan, said the research had demonstrated the ability to manipulate the molecular properties of the nanotube to fabricated nanoscale electrical device.
Transistors, which are used to switch and amplify electronic signals, are often called the "building blocks" of all electronic devices, including computers. For example, Apple says the chip which powers the future iPhones contains 15 billion transistors.
The computer industry has been focused on developing smaller and smaller transistors for decades, but faces the limitations of silicon.
In recent years, researchers have made significant steps in developing nanotransistors, which are so small that millions of them could fit onto the head of a pin.
"Miniaturization of transistors down to nanometer scale is a great challenge of the modern semiconducting industry and nanotechnology," Professor Golberg said.
"The present discovery, although not practical for a mass-production of tiny transistors, shows a novel fabrication principle and opens up a new horizon of using thermomechanical treatments of nanotubes for obtaining the smallest transistors with desired characteristics."

Betcha you could put a lot of them into a syringe.
YET another major item on my resume is going to become irrelevant.
Technlogy marches on. Dang!
"plasma etch/deposition chamber processing of the nanometer scale photo-lithographed silicon wafers"
Chilarity. Gotta hand it to the author for attempting to explain the direction of the twist in the nanotube while threading his way into missing the point.
It’s all Greek to me.
Well played!

The Covid (so called) vaccine based upon nano particles and mRNA fragments created by computer within an extruded graphineoxide frame has been possible for more than 10 years, but as I understand, until recently it was not possible to mass produce it in global scale.
If they discover a new tool, you just MUST put it to use for something.
In this case is defies all sense of humanity that this Covid response is being applied.
Thank you for posting.

I’m just chillin’. In Cedar Rapids.
That was my reaction.
