发明名称 OPTOELECTRONIC SEMICONDUCTOR CHIP
摘要 <p>An optoelectronic semiconductor chip, based on a nitride material system, comprising at least one active quantum well, wherein during operation electromagnetic radiation is generated in the active quantum well, the active quantum well comprises N successive zones in a direction parallel to a growth direction z of the semiconductor chip, N being a natural number greater than or equal to 2, the zones are numbered consecutively in a direction parallel to the growth direction z, at least two of the zones have average aluminium contents k which differ from one another, and the active quantum well fulfils the condition: 50≰∫(35−k(z))dz−2.5N−1.5∫dz≰120.</p>
