Abstract
Graphene, an atomically thin allotrope of carbon, shows promise for use as a biosensor due to its sensitivity to local voltage changes. To consider making practical sensors, it is necessary to understand the fundamental noise limits of the sensor. In particular, for the first time, we considered the thermally-driven “liquid-gate Johnson noise” of graphene field effect biosensors. We found fluctuations with a 1/fp dependence, with p = 0.75-0.85. These results explain noise spectra previously measured through liquid gated graphene devices and predict targets for future device performance.
