Gas detection systems and methods using graphene field effect transistors

摘要: A gas detection system for selectively detecting one or more gases from a mixture of includes sensor that at least graphene field effect transistor (GFET). The GFET source electrode, drain channel layer, gate electrode arranged proximate the and dielectric layer between electrode. also modulation electrically connected to modulate response sample, detector detect modulated signal containing information concerning sample during by system, processor configured communicate with receive signal. is further determine concentration in based on
