  • Broadband radiation sensor based on a resonantly-coupled graphene SNS junction
    Patent number: 11921141
    Abstract: A graphene-based broadband radiation sensor and methods for operation thereof are disclosed. The radiation sensor includes an electrical signal path for carrying electrical signals and one or more resonance structures connected to the electrical signal path. Each resonance structure includes a resonator having a resonant frequency. Each resonance structure also includes a graphene junction connected in series with the resonator, the graphene junction including a graphene layer and having an impedance that is dependent on a temperature of the graphene layer. Each resonance structure further includes a heating element that is thermally coupled to the graphene layer and is configured to receive an incident photon, where the temperature of the graphene layer increases in response to the heating element receiving the incident photon.
