New generation of flexible graphene transistors
Making electronic components using graphene, a material composed of a single layer of carbon atoms, is one of today's major technological challenges. Researchers hope to harness the outstanding electron mobility of graphene and also use the material to design low-cost, flexible electronics. Research teams from CEA, CNRS, Université de Lille 1 and Northwestern University have come up with a novel process for manufacturing transistors that combine flexibility and electron mobility and are capable of working at very high frequencies in the GHz range. The process uses a form of graphene in solution that is compatible with printing techniques. Electronic components such as these should lead to the development of high-performance electronic circuits built into everyday objects.
