Abstract
Terahertz (THz) radiation detectors based on the rectification of a THz signal via the non-linear Hall effect in thin films of non-centrosymmetric layered topological semimetals are provided. The THz detectors, which enable sensitive, broadband, and fast room-temperature terahertz radiation detection, can be fabricated with electrostatic gates to tune the terahertz rectification.
