Abstract
Double-graphene-layer (DGL) heterostructures have attracted attention due to their various potential applications in optical modulation, terahertz (THz) emission/detection, and THz photo-mixing [1] and many more. Here, we report on experimental observation of the THz emission and detection in the DGL structures and demonstrate that the photon-assisted resonant radiative inter-GL transitions enable the applications of such devices for THz lasers and photodetectors (PDs) [2].
