Abstract: The paper presents the main aspects of the hot-electron effect in superconducting films, focusing on the applications of this effect in detectors of electromagnetic radiation. Within the framework of linearised heat balance equations analytic expressions have been obtained for the voltage responsivity and  noise temperature of such hot-electron detectors.

Keywords: hot-electron effect in superconductors, detectors of electromagnetic radiation.
