FIELD: physics.
SUBSTANCE: high-speed and miniature detection system, particularly for detecting electromagnetic radiation in the gigahertz and terahertz range, has a semiconductor structure, having a two-dimensional layer of charge carriers or a quasi-two-dimensional layer of charge carriers with one defect or multiple defects, at least first and second contacts for the charge carrier layer and a device for measuring the photoelectromotive force between the first and second contacts. Operation of the system according to different implementations is based on resonant excitation of plasma waves in the semiconductor structure.
EFFECT: enabling detection of electromagnetic radiation in the gigahertz and terahertz range using a high-speed and miniature detection system.
