Abstract
An optoelectronic semiconductor chip includes a semiconductor layer sequence having at least one doped functional layer having at least one dopant and at least one codopant, wherein the semiconductor layer sequence includes a semiconductor material having a lattice structure, one selected from the dopant and the codopant is an electron acceptor and the other an electron donor, the codopant is bonded to the semiconductor material and/or arranged at interstitial sites, and the codopant at least partly forms no bonding complexes with the dopant.
