Electrochemical Characterisation of CVD Grown Graphene

Heavily overlapping diffusion layers, observed for the outer-sphere redox probe 

In the first case, if the graphene film has a greater electrochemical activity over that of the underling metal surface, such that K,etaisurface grown 

a really unique response might be observed, which was discussed in Sect. 3.1.2 with respect to HOPG electrode surfaces, such that two voltammetric peaks might be observed In this case a first peak would arise from a material exhibiting fast electron transfer and a second peak from the graphene surface. The 

It is evident, due to the above scenarios, that the electrochemistry of CVD grown graphene is highly fascinating. This section has also highlighted that materials scientists can beneficially utilise electrochemistry as a tool to assist in the characterisation of their fabricated graphene material.
