Chemical vapour sensing using power spectrum of 1/f noise of graphene

In this paper we present a method for sensing of chemical vapour based on scaling of resistance fluctuation of single layer graphene (SLG) field effect transistors. Increase of variance of resistance fluctuation of device in presence of chemical vapour makes noise a very sensitive tool for detection. Analysis of the effect of presence of chemicals in the ambience of graphene on the 1/f noise spectrum is analyzed. Change in noise presents a method of detection with sensitivity and specificity, with response times much smaller than timescales related to resistance change.
