NOVELTY - Single-layer graphene terahertz thermoelectric detector construction and verification method, involves constructing a full-dielectric substrate. Single layer graphene is obtained. A single-layer graphene terahertz thermoelectric detector is constructed based on the full-dielectric substrate. X-polarization terahertz wave is used to verify the single-layer graphene terahertz thermoelectric detector to obtain temperature difference potential and a photoelectric voltage signal. USE - Single-layer graphene terahertz thermoelectric detector construction and verification method. ADVANTAGE - The method enables constructing and verifying single-layer graphene terahertz thermoelectric detector with simple operational steps, accurately controlling the incident light spot position, and allowing terahertz light spot covering the whole photosensitive region.
