Abstract
A light emitting diode has a substrate body consisting of silicon carbide, which is transmissive for the luminescent radiation generated by the diode. The diode has a first epitaxially deposited layer, consisting of silicon carbide of a first conductivity type, disposed on the substrate body, and a second epitaxially deposited layer of silicon carbide of a second conductivity type disposed on the first layer. The diode has one electrode connected to the second layer and another electrode connected to an exposed portion of the first layer.
