Exploiting the IR Transparency of Graphene for Fast Pyroelectric Infrared Detection

is thus an intriguing and unique electrode material for use in pyroelectric infrared detection. Pyroelectric detectors operate by converting radiation into heat, which subsequently elicits a current proportional to the intensity of incident light. Conventionally, these sensors com-prise a pyroelectric material sandwiched between two elec-trodes. The top electrode serves both as an electrical conductor, as well as an absorption layer that conducts heat from incident radiation to the pyroelectric.
