Graphene transistors in high-performance demonstration

The hope for the “miracle material” graphene to fulfil its promise in electronics has received a boost – by changing the recipe when cooking it. Graphene, one-atom-thick sheets of carbon, can carry electric charges far faster than currently used materials. But it has proven difficult to make it behave as a semiconductor like silicon, or

Graphene holes ‘heal themselves’

Graphene – the “wonder material” made of sheets of carbon just one atom thick – undergoes a self-reparing process to correct holes, researchers report. Graphene’s outstanding mechanical strength and electronic properties make it a promising material for a wide range of future applications. But its almost ethereal thinness makes it easily damaged when working with
