  Graphene is a two-dimensional material consisting of a single layer of carbon atoms arranged in a hexagonal lattice.  It is known for its exceptional mechanical, thermal, and electrical properties, and has potential applications in areas such as electronics, energy storage, and biomedicine. Graphene can be produced using several methods, including: 1.      Mechanical exfoliation: This involves peeling off thin layers of graphene from graphite using adhesive tape. 2.      Chemical vapour deposition (CVD): In this method, a hydrocarbon gas such as methane is passed over a metal catalyst at high temperatures, causing carbon atoms to deposit and form a graphene layer on the surface. 3.      Epitaxial growth: This involves growing graphene on a substrate using a process similar to CVD, but with the addition of a carbon-rich gas. 4.      Reduced graphene oxide (rGO): This involves chemic...
