Phonon-Mediated Mid-Infrared Photoresponse of Graphene
Phonon-Mediated Mid-Infrared Photoresponse of Graphene
The photoresponse of graphene at mid-infrared frequencies is of high technological interest and is governed by fundamentally different underlying physics than the photoresponse at visible frequencies, as the energy of the photons and substrate phonons involved have comparable energies. Here, we perform a spectrally resolved study of the graphene photoresponse …
