Graphene-based electronic devices for radiation detection and thermosensing
Paper i proceeding, 2024

Single-layer-CVD graphene is grown and integrated into passive electronic interfaces through a cost-effective optical fabrication approach. Raman characterizations are carried out to verify the single-layer nature of the grown graphene. The realized antenna-free, non-gated, and passive electronic device with Ge/Au contacts to graphene shows radiation detection (94 GHz) and thermosensing (6K-120 K) based on the radiation-induced thermoelectric effects in graphene. Further, a Ti/Au contacted graphene electronic device is fabricated and characterized through current-voltage measurements at cryogenic temperatures (7-140 K). Ti-Au contacted electronic device shows thermo-resistive sensing that is applicable to negative temperature coefficient (NTC) thermistors. Application and future scopes of these graphene radiation detectors and thermosensors can be in temperature monitoring in graphene-integrated electronic and quantum devices, terahertz communications, thermal imaging, space, and environmental monitoring.
