    摘要: An optoelectronic semiconductor component comprising a semiconductor layer sequence (3) based on a nitride compound semiconductor and containing an n-doped region (4), a p-doped region (8) and an active zone (5) arranged between the n-doped region (4) and the p-doped region (8) is specified. The p-doped region (8) comprises a p-type contact layer (7) composed of InxAlyGa1-x-yN where 0≦x≦1, 0≦y≦1 and x+y≦1. The p-type contact layer (7) adjoins a connection layer (9) composed of a metal, a metal alloy or a transparent conductive oxide, wherein the p-type contact layer (7) has first domains (1) having a Ga-face orientation and second domains (2) having an N-face orientation at an interface with the connection layer (9).
