Graphene – the high-potential allotrope of carbon, which is made of a hexagonal-honeycomb array of sp2 hybridized carbon atoms – has been attracting the attention of nanotechnology researchers for the past couple of decades. The properties of other forms of carbon-like fullerenes (buckyballs-C60), carbon nanotubes and even graphite are derived from the concept of this as then hypothetical single layer of carbon. By the beginning of the previous decade, people started realizing this one atom thick layer. Since then it has been a platform for scientists to think about exotic phenomena like the room-temperature quantum hall effect and half integer quantum hall effect. The material exhibits some superior properties such as the highest mobility for a non-superconducting material along with the highest value for young’s modulus, which is a measure of mechanical strength.
