An Exploration Of The Use Of Electrochemical Impedance Spectroscopy Of Epitaxial

Electrochemical impedance spectroscopy (EIS) was used to analyze the impedance of epitaxial graphene as the graphene was exposed to substances such as air, de-ionized water, and acetone fumes. The results indicated that the graphene did respond to exposure to different substances; however, it was also clear that the graphene was too sensitive to exposure and therefore could not be used in this way to differentiate between different substances. In fact, the results for tests on different substances were, on average, more similar than the results for multiple tests on the same substance
