Detecting electromagnetic waves in the terahertz frequency range remains a challenging problem. Researchers from the University of Cambridge, together with physicists from the University of Augsburg, have recently discovered a new physical effect which could change that. In a new study, the scientists are now developing a theory explaining the mechanism behind it. Their findings make it possible to construct small, inexpensive, and highly sensitive terahertz detectors. These could be used, for example, in medical diagnostics, for contactless security checks, or for faster wireless data transmission. The results of the new theory have been published in the journal Physical Review B.
