Abstract
A system includes a semiconductor substrate having at least two electrodes disposed thereon, a dielectric layer disposed over the electrodes, a graphene layer disposed over the dielectric layer and electrically isolated from the electrodes, and a differential amplifier operatively connected to the electrodes and electrically isolated from the graphene layer. A radiation-sensitive layer may be disposed over the graphene layer and a voltage source may be operatively connected to two of the electrodes. The system may be contained on an integrated circuit and may be used to sense radiation in liquid and gas form.
