Abstract
We propose a novel concept for FIR light detection by means of Hall de vices biased at strong currents. The base of the device operation is t he effect of photoinduced breakdown of the integer quantum Hall effect (QHE). We demonstrate experimentally that the increase of the bias cu rrent from 100 to 300 mu A leads to the photoresponse enhancement by o ver two orders of magnitude, Application of the presented results for designing a tunable high sensitive FIR photodetector is discussed.
