Can graphene detect single microwave photon?
Kin Chung FongCalifornia Institute of Technology
Graphene is a material with remarkable electronic properties. However the electronic thermodynamic properties of this two-dimensional Dirac Fermions are less explored. I will discuss our specific heat capacity, Wiedemann-Franz, and electron-phonon thermal conductance using Johnson noise thermometry developed for graphene . These measurements suggest that graphene-based devices can generate substantial advances in the areas of ultra-sensitive bolometry, calorimetry, microwave, and terahertz single photo-detection for applications in areas such as observational astronomy, quantum information and measurement.
