Graphenes now go monolayer and single crystalline

IBS-CMCM scientists have reported a truly single layer (i.e., adlayer-free) large area graphene film on large area copper foils. They refined the chemical vapor deposition (CVD) growth method by eliminating all carbon impurities inside the copper foils on which graphene is grown. This uniform, "perfect" single layer, single crystal graphene is expected to find use as an ultrathin support material for high-resolution transmission electron microscopy imaging, and in optical devices. Also as an appropriate graphene to achieve extremely uniform functionalization which leads to many other applications, particularly for sensors of various types.
