One step closer to making terahertz technology usable in the real world

"new physical effect when two-dimensional electron systems are exposed to terahertz waves... distinguish medicines from illegal drugs and explosives... faster wireless communications beyond the state-of-art... high frequencies, matter absorbs light in photons... release electrons by incident photons... three-dimensional case, electrons... expelled into vacuum by photons in ultraviolet or X-ray range, or released into a dielectric in mid-infrared to visible range... terahertz detectors with substantially higher sensitivity"
