Electron Transfer Kinetics at Graphene Electrodes

In situ Raman spectroscopy can be used to identify if a sample is n- or p-doped and can provide insight into the impact on Cq [90] (see Equation 4.7)  

More research is required to gain a deeper insight and understanding of the Cj, of graphene electrode. Studies using well-defined samples are vital, where there are no contributions from the production or transfer process. Information on the electrical properties of the material would aid in determining the local DOS [94] and hence provide a greater ability to tune the electrode properties for the desired applications. 

As noted earlier, several unique properties of graphene, namely high electron mobility, high specific surface area, flexibility, and high transparency, could
