The operation of a previously proposed terahertz (THz) detector is formulated in detail. The detector is based on the hot‐electron effect of the 2D electron gas (2DEG) in the quantum well (QW) of a GaAs/AlGaAs heterostructure. The interaction between the THz radiation and the 2DEG, the current enhancement due to hot‐electron effect, and the noise performance of the detector are analyzed. © 2003 Wiley Periodicals, Inc.
