摘要

Radiation-emitting semiconductor component (1) comprises a current expanding layer (9) arranged on the n-conducting side of a semiconductor body and in an electrical conducting connection with a semiconductor layer sequence (3). The current expanding layer is permeable for radiation and contains a material which is a donor with respect to the n-conducting side of the layer sequence.
