Graphene is an allotropic form of carbon which has a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice. Each carbon atom in a graphene sheet is connected to three other atoms by a sigma bond. It exhibits unusual electronic properties and is considered a semimetal. While the two dimensional structure is termed as graphene, the three dimensional structure is referred to as graphite. It is a good conductor of heat and absorbs light of all visible wavelengths. It can be produced through various techniques such as fullerene splitting, nanotube slicing, epitaxy, sodium ethoxide pyrolysis, etc. Graphene finds extensive application in various devices such as solar cells, touch panels, light emitting diodes and sporting equipment. This book includes some of the vital pieces of work being conducted across the world, on various topics related to graphene materials. It includes contributions of experts and scientists which will provide innovative insights into this field.
