Synthesis of Graphene

Abstract

Single layer graphene is called monolayer graphene which exhibits some unique characteristics with a special arrangement of atoms in its crystal. In contrary, graphene can be sometimes modified for numerous application specific uses. This book chapter presents brief details of graphene structure, along with formation of sp2 hybridization, critical parameters of the unit cell, formation of σ and π bonds, different properties, synthesis processes and their advantages and disadvantages over one another, potential applications of graphene in different fields. Out of different synthesis processes, mechnical exfoliation, chemical exfoliation, reduced graphene oxide, chemical vapour deposition, and epitaxial growth are the most well-known processes, and are detailed and described here. Graphene application in integrated circuit, optical electronics generally in OLED, energy application generally for the storage purpose is elaborately discussed here in this chapter. Throughout the chapter the authors described everything with suitable diagrams as per the requirements.
