Gas-Selective Signal Amplification in Fluctuation-Based Graphene FET Sensors

The power spectrum of conductance fluctuations arising from the adsorption of gas molecules to a graphene field-effect transistor was shown to contain the signature of the adsorbing species recently. A detailed mechanism of the phenomena was not provided although it was remarked that these conductan...
