Researchers have shown that double-layer graphene can function both as a superconductor and an insulator, a property that could revolutionize transistor technology. This dual functionality allows for the development of nanoscale transistors that are highly energy-efficient.
An international research team led by the University of Göttingen has demonstrated experimentally that electrons in naturally occurring double-layer graphene move like particles without any mass, in the same way that light travels. Furthermore, they have shown that the current can be “switched” on and off, which has potential for developing tiny, energy-efficient transistors – like the light switch in your house but at a nanoscale. The Massachusetts Institute of Technology (MIT), USA, and the National Institute for Materials Science (NIMS), Japan, were also involved in the research. The results were published in the scientific journal Nature Communications.
