IntroductionGraphene has received a great deal of media coverage since Geim and Novoselov published their results on single-crystalline graphite films in 2004, which earned them the Nobel Prize in Physics in 2010. (Novoselov et al, 2004) It has been described by the mass media as the wonder substance or super material, not only because it is the thinnest material ever known and the strongest ever measured, but also because of its excellent electrical properties, thermal, mechanical, electronic and optical properties. It has high specific surface area, high chemical stability, high optical transmittance, high elasticity, high porosity, tunable band gap, and ease of chemical functionalization that helps fine-tune its properties ( Geim et al, 2007). Furthermore, graphene has a multitude of amazing properties such as the half-integer quantum Hall effect at room temperature (Novoselov et al, 2007), long-range ballistic transport with an electron mobility almost ten times greater than that of silicon, and the availability of Charge carriers that behave like massless relativistic quasi-particles, known as Dirac fermions. (Geim et al, 2007) The exceptional electrical conductivity, transparency and flexibility of the graphene-based material have led to the research and development of some future technologies, such as flexible and wearable electronics. Furthermore, graphene can also be used for efficient energy storage materials, polymer composites and transparent electrodes. (Geim et al, 2007) This article presents a brief overview of the structure and some properties of graphene, along with a presentation of the graphene synthesis method and various applications.
