Abstract
We report on in-situ graphene growth studies on nickel, copper and platinum catalysts inside a modified environmental scanning electron microscope (ESEM). The method enables a direct observation of the dynamic processes that occur during a complete CVD process, involving substrate annealing, graphene nucleation and growth and finally, substrate cooling. Watching the formation of single atom thin sheets of carbon enables direct kinetic and mechanistic studies in a novel and unparalleled way.
