Growth and Characterization of Graphene via Chemical Vapour Deposition (CVD)

Abstract

Graphene is a two-dimensional (2D) material with a single atomic layer of carbon atoms, with unique properties such as high electrical and thermal conductivity, high optical transparency and tensile strength. It can be fabricated by mechanically exfoliation from bulk graphite, since graphite is made of the stacked layers of graphene bonded together by Van der Waals (VdW) forces. Graphene has a great potential to be used in flexible ultra-sensitive sensor applications, or as transparent conductive layer in displays and solar cells. However, a major issue in graphene commercialization is the difficulty in scaling up high-quality graphene production efficiently and cost-effectively.
