Electromagnetic radiation-emitting semiconductor component used as an illuminating diode has an electrically conducting covering layer which is p-doped using carbon to produce good electrical conductivity

摘要

Electromagnetic radiation-emitting semiconductor component comprises a semiconductor sequence (14) having an active layer (22) emitting photons, and an electrically conducting covering layer (16) made from InxGayAl1-x-yP (where y = 0-1; x = 0-1; and x + y = not more than 1), especially GaP, arranged on the layer sequence and permeable for the photons emitted by the active layer. The covering layer is p-doped using carbon to produce good electrical conductivity. An Independent claim is also included for a process for the production of an electromagnetic radiation-emitting semiconductor component.
