Bilayer Graphene Could Usher in New Tunnel Transistor

Researchers at the Moscow Institute of Physics and Technology (MIPT) have proposed a new tunnel transistor based on bilayer graphene that could reduce its power consumption, allowing a significant increase in processors’ clock speeds. In their simulations, the MIPT researchers calculated that the clock speed could be increased by as much as two orders of magnitude. “The point is not so much about saving electricity—we have plenty of electrical energy,” said Dmitry Svintsov of MIPT in a press release. “At a lower power, electronic components heat up less, and that means that they are able to operate at a higher clock speed—not one gigahertz, but ten for example, or even one hundred.” Tunneling transistors have become an increasingly attractive alternative to traditional transistors that operate on the basis of electronic barriers that block electrons from passing through.
