Patent ID: 10840411

Abstract:
A semiconductor layer sequence is disclosed. In an embodiment the semiconductor layer sequence includes an n-conducting n-region, a p-conducting p-region and an active zone having at least one quantum well located between the n-region and the p-region, wherein the semiconductor layer sequence includes AlInGaN, wherein the n-region comprises a superlattice, wherein the superlattice has a structural unit which repeats at least three times, wherein the structural unit comprises at least one AlGaN layer, at least one GaN layer and at least one InGaN layer, wherein an intermediate layer is disposed between the active zone and the superlattice, wherein the intermediate layer comprises either n-doped GaN or n-doped GaN together with n-doped InGaN so that the intermediate layer is free of aluminum, and wherein the intermediate layer directly adjoins the active zone and the superlattice.
