1. Introduction to Graphene
Graphite, which is used for pencil lead and is familiar to us, is a structure in which carbon layers are piled up as nets arranged like honeycomb hexagonal nets. This layer of graphite is called graphene. Graphene is 0.2 nm thick and has very high physical and chemical stability. In 2004, researchers from Britain’s Andre Geim and Konstantin Novoselov succeeded in separating graphene from graphite using transparent tape at room temperature, winning the 2010 Nobel Prize for Physics.
