Graphene transistor was discovered in 2007 by Professor Andre Geim and his team of researchers at Manchester Centre for Mesoscience and Nanotechnology. A graphene transistor, also known as a single-electron transistor, is a nanotechnology transistor made of a material similar to graphite (allotrope of carbon) and with conductivity and electrical properties much simpler and more efficient than silicon. This single-electron transistor allows one
