IntroductionGraphene has received a lot of media coverage since Geim and Novoselov published their findings on single-crystal graphitic films in 2004, earning them the Nobel Prize in Physics in 2010. (Novoselov et al, 2004) It has been described as the miracle substance or super material by the media, not only because it is the thinnest material ever known and the strongest never measured, but also because of its excellent electrical, thermal, mechanical, electronic and optical properties. properties. It has high specific surface area, high chemical stability, high optical transmission, high elasticity, high porosity, tunable bandgap and ease of chemical functionalization which helps in tuning its properties (Geim et al, 2007). Additionally, 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 almost ten times higher electron mobility than that of graphene. 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 and transparency and flexibility of graphene-based materials have led to the research and development of some future technologies, such as flexible and wearable electronics. In addition, graphene can also be used to make efficient energy storage materials, polymer composites, and transparent electrodes. (Geim et al, 2007) This article provides a brief overview of the structure and some properties of graphene, as well as an overview of the graphene synthesis method and various applications.
