(a). Nyquist plot for graphene-coated and pristine P-Si based on EIS sample characterization, with knee frequencies labeled in the plot. (b). Cyclic Voltammetry measurements for graphene-coated and pristine P-Si, with approximate electrochemical windows in EMIBF4 electrolyte environment labeled, and (c). through-plane electrical measurement I-V curves of graphene-coated and pristine P-Si samples emphasizing a dramatic decrease in sample resistance due to the presence of graphene.
