...researchers from Rensselaer Polytechnic Institute and the University of Virginia have reported the first implementation of a terahertz detector utilizing a 2D electronic fluid in a HEMT which operated at 2.5 THz. Called plasma wave, the terahertz radiation is detected by the HEMT as a result of an induced DC drain-to-source voltage proportional to the radiation intensity. [21]
