Scientists Turn Carbon Nanotubes into Tiny Transistors materialsscience science
Using a transmission electron microscope, a team of materials scientists led by the International Center for Materials Nanoarchitectonics in Japan and the Queensland University of Technology has created a carbon nanotube transistor that’s 25,000 smaller than the width of a human hair.
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. The heat and strain then changed the chirality 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.
“Semiconducting carbon nanotubes are promising for fabricating energy-efficient nanotransistors to build beyond-silicon microprocessors.”
