Experimental results are reported of high-frequency (∼ THz) radiation detection by metal-metal point contacts at low temperatures as a function of bias voltage. The dominant detection mechanism can be attributed to rectification due to electron-phonon-scattering-induced nonlinearity of the I-V characteristics, a process not observed before.
