A semiconductor component for detecting electromagnetic radiation includes
a contact between a metal and a semiconductor. The semiconductor has at
least one metal-chalcogenide compound semiconductor as an optical
absorbing material or is configured completely from said semiconductor.
This allows a cost-effective component to be produced which reacts to
electromagnetic radiation in a specifically defined manner. The
semiconductor component can be used in an electronic component and a
sensor system. A method is also described for producing a semiconductor
component by bringing a substrate into contact with a solution, in which
a precursor of metal-chalcogenide compound semiconductor is dissolved
and/or suspended.
