Abstract
A semiconductor radiation detector with layer-wise construction and a contive region having a two-dimensional or quasi one-dimensional electron or hole gas is provided in which adiabatic transport in edge channels occurs at least regionally and in which at least two contacts are provided to this conductive region. The transport in the edge channels is disturbed by interaction with the electromagnetic radiation to be detected, i.e. an increase of the scattering rate between the edge channels is caused. This leads to a change of the resistance measurable between the contacts, with a means being provided for measuring the change of resistance to thereby detect the incident radiation.
