Performance of Graphene Thermal Photon Detectors

Understand

We analyze the performance of graphene microstructures as thermal photon detectors and deduce the range of parameters that define a linear response.

• The saturation effects of a graphene thermal detector that operates beyond the linear range are described in detail for a single-photon detector (calorimeter).
• We compute the effect of operating beyond this linear range and find that sensitive detection occurs for such non-linear operation.
• We identify the optimum conditions and find that single-photon detection at terahertz (THz) frequencies should be feasible.
