Synthesis of Single-layer Graphene: A Review of Recent Development

Since graphene has been successfully synthesized in year 2004, graphene has become the highlight of the research study in the material science field because of its peculiar properties and attracted a large amount of research for its application. The extraordinary properties of graphene show some promising applications such as optical electronics, photovoltaic systems, composites and others. However, it is found that the production of single layer graphene for commercial application still under research for improvement of its quality, size and amount. It has been reported that single-layer graphene can be synthesized using several methods, but the most promising method to synthesize high quality single-layer graphene is chemical vapour deposition (CVD). In this review, current development of the synthesis of single layer graphene and its future prospects is presented and discussed.
