Abstract :
We observed intensive room temperature broadband terahertz emission from two-dimensional plasmons in dual grating-gate high electron-mobility transistors. Experiments were performed using infrared spectroscopy with a silicon bolometer. Simulation reveals the thermal excitation of the plasmons.
