Graphene photon detector works from infra-red to terahertz

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have developed a graphene optical detector that responds to incident electromagnetic radiation from infra-red to terahertz, and works at room temperature. It has already been used to synchronise two lasers. It consists of graphene on silicon carbide, with inter-digitated electrodes connected to a log-periodic antenna (see photo). “In contrast to ...
