Abstract

We discuss the prospects for using graphene as an ultrasensitive detector of THz photons. In our analysis, we examine two contacting schemes: superconducting contacts which make good Ohmic contact to the device and superconducting contacts with a thin insulating barrier. We perform thermal measurements of large area graphene devices to extract information on the electron-phonon coupling in graphene. Using these results, we develop predictions for optimum detector performance. With ideal biasing conditions and device parameters, we find that an NEP of 2 × 10-19 W/√Hz should be achievable.
