Abstract:
The present invention relates to a p-doped contact for use in a light-emitting diode for the ultraviolet spectral range, comprising a p-contact layer having a first surface for contacting a radiation zone and a second surface comprising, on the side facing away from the first surface: a) a coating, which directly contacts 5%-99.99% of the second surface of the p-contact layer and contains or consists of a material having a maximum reflectivity of at least 60% for light with a wavelength of 200 nm to 400 nm; b) a plurality of p-injectors, which are disposed directly on the second surface of the p-contact layer.
