Terahertz Detection: Extreme Sensitivity of Room-Temperature Photoelectric Effect for Terahertz Detection (Adv. Mater. 1/2016).

Terahertz (THz) is the gap between infrared and microwave frequencies. THz detection is still a formidable challenge even though no suitable theory has been built until now, although considerable mechanisms have been proposed. On page 112, Z. Huang and co-workers propose a unique theory to realize an excellent photoelectric effect and experimentally demonstrate its extreme sensitivity to room-temperature THz detection.
