✦ Synopsis
We use a semiclassical description for an analysis of the detection of THz-photons by electrons performing Bloch oscillations in a semiconductor superlattice. We show that the current responsivity of the superlattice detector can nearly reach the quantum efficiency e/hω at room temperature if the superlattice is matched to the THz radiation.
