Abstract
In this paper, we present a hot-electron bolometric detector, which uses the nonlinearities of the heated two-dimensional electron gas medium in AlGaAs/GaAs at room temperature. The cooling process of the electrons is through the phonon-scattering mechanism. The response was measured at the 0.1–0.2 THz frequency range. The response was estimated, showing possible application of these detectors in sensing of Terahertz radiation.
