A portion of the electromagnetic wave spectrum between ∼0.1 and ∼10 terahertz (THz) suffers from the lack of powerful, effective, easy-to-use, and inexpensive emitters, detectors, and mixers. We propose a multilayer graphene—boron-nitride heterostructure which is able to emit radiation in the frequency range ∼0.1–30 THz with the power density up to ∼0.5 W/cm2 at room temperature. The proposed device is extremely thin, light, flexible, almost invisible, and may become an important member of the family of devices operating at terahertz frequencies.
