Abstract
A II-VI semiconductor component is produced with an active layer sequence having at least one II-VI semiconductor layer containing Se and/or S on a substrate. First, an Se-free II-VI interlayer based on BeTe is grown epitaxially on the substrate in an essentially Se-free and S-free first epitaxy chamber. The active layer sequence is then grown epitaxially on the Se-free II-VI semiconductor layer.
