What is Graphene?
Graphene is a single layer carbon atoms’ arrangement in a two dimensional hexagonal lattice. You can try to visualize flat mesh made from chicken wire, but in this case, this metaphoric is shifted to the microscopic level. Every carbon atom in graphene is connected with three other carbon atoms, and it provides a material which is both nearly indestructible and almost weightless.
This material was first isolated and characterised in year 2004 by two physicists named Andre Geim and Konstantin Novoselov, who used this material for winning the noble prize in the field of physics in the year 2010. Since then people have shown a lot of interest in graphene due to its superior properties.
