Chapter 2 - CVD Synthesis of Graphene

Abstract

Graphene has generated vast interest in various field, due to its excellent electrical, optical, mechanical and thermal properties, which has motivated huge interest in its production in a controllable and scalable manner. Amongst various synthetic approaches, chemical vapor deposition (CVD) possesses unique advantages with regards to large-scale synthesis of high-quality and uniform graphene, where graphene can be prepared in the forms of either 3D powders or 2D thin films. The substrates for graphene growth, including metallic substrate, semiconductor, insulating substrate, is designable for diverse applications. The focus here is concentrated on the CVD strategies for synthesizing graphene with controllable domain size, thickness and scalability, and potential applications of graphene, underlying mechanism and potential applications of 2D and 3D graphene on a variety of substrates.
