Graphene is a one-atom thick sheet of carbon atoms arranged in a honeycomb lattice. It has remarkable properties such as being very strong yet flexible. The document discusses the history and invention of graphene, its properties such as high conductivity and flexibility, and its advantages over silicon. Potential applications of graphene discussed include use in computer processors, memory, touchscreens, cameras, and for enabling high-speed internet. The future of graphene supercomputing and its potential to replace silicon is also examined, along with some current limitations.
