    • The invention relates to a radiation-emitting semi-conductor element provided with a layered structure, comprising an n-doped confinement layer (14), a p-doped confinement layer (22), and an active layer (18) emitting photons, said layer being arranged between the n-doped confinement layer (14) and the p-doped confinement layer (22). According to the invention, the n-doped confinement layer (14) is doped with a first n-dopant (or two n-dopants which are different from each other) in order to produce a high active doping and a precise doping profile, and the active layer (18) is doped with exclusively one second n dopant, which is different form the first dopant, in order to improve the layer quality of the active layer (18).
    • 本发明涉及设置有分层结构的发射辐射的半导体元件,其包括n掺杂限制层(14),p掺杂限制层(22)和发射光子的活性层(18),所述 层设置在n掺杂限制层(14)和p掺杂限制层(22)之间。 根据本发明,为了产生高活性掺杂和精确的掺杂分布,n型掺杂限制层(14)被掺杂有第一n型掺杂剂(或者彼此不同的两种n型掺杂剂),并且 为了改善有源层(18)的层质量,有源层(18)仅掺杂有与第一掺杂剂不同的第二n掺杂剂。
