Professors Sanjay Banerjee and Emanuel Tutuc have demonstrated, for the first time, that centimeter-square areas of copper foils can be covered almost entirely with mono-layer graphene bringing this intriguing material one step closer to commercial viability. Graphene, formed with carbon atoms linked together like nanoscopic chicken wire, holds great potential for nanoelectronics. It also shows promise for electrical energy storage, for use in composites, for thermal management, in chemical-biological sensing, and as a new sensing material for ultra-sensitive pressure sensors.
