Graphene Nanobolometers for Ultrasensitive Far-Infrared Detection

Daniel Prober – Yale University

Graphene has recently been proposed as an ultrasensitive THz photon detector for space-based astronomy observations.  We have studied the thermal properties of monolayer graphene for this application, and done extensive modeling of the detection processes.  One would employ superconducting contacts to achieve energy confinement in the graphene.  Recently we have studied experimentally the energy loss processes in graphene down to T = 0.1 K.  The space-based observatories that could employ such detectors will be outlined, as well as the science that can be done with these observatories.
