Graphene and its Dopants used as a Transistor in VLSI Circuits

Graphene, a sheet of carbon atoms arrayed in a honeycomb pattern, could be a better semiconductor than silicon. Due to many such properties graphene has been under study as an alternative substance used, rather than graphite and silicon in transistors. But the main function of a transistor is to perform the operation of switching, i.e. on and off. The problem that arises here is that graphene has no energy band gap and therefore in this paper, the author reviews the various possibilities with which a band gap can be induced in graphene and with all the possible alternatives of use of graphene in LSIs.
