Researchers from the University of Manchester have built on their work with graphene by creating nanometre scale transistors from a single graphene crystal.
According to the researchers, graphene transistors start showing advantages and good performance at sizes of less than 10nm. “Previously, researchers tried to use large molecules as individual transistors to create a new kind of electronic circuits. It is like a bit of chemistry added to computer engineering,” said Dr Kostya Novoselov of the School of Physics and Astronomy. “Now one can think of designer molecules acting as transistors connected into designer computer architectures on the basis of the same material (graphene) and use the same fabrication approach that is currently used by semiconductor industry.”
However, Professor Andre Geim counselled: “It is too early to promise graphene supercomputers. Unfortunately, no existing technology allows the cutting of materials with true nanometre precision. But this is exactly the same challenge that all post silicon electronics has to face. At least we now have a material that can meet such a challenge.”
