Title: LIGHT EMITTING DIODE AND METHOD FOR PRODUCING A LIGHT EMITTING DIODE
Abstract:
A light emitting diode (100) has a layer sequence (1) having an active layer (10) emitting radiation during operation, at least one supply element (3), which is arranged on a first main side (11) of the layer sequence and is used to route electric current into or out of the layer sequence (1) during operation, and a tunnel layer (2) between the active layer (10) and the supply element (3). The supply element (3), in plan view, is partly or completely covered by the active layer (10) and the tunnel layer (2). Between the supply element (3) and the layer sequence (1), a flow of current is possible only by virtue of a tunnel effect. In the region of the supply element (3), at least two subregions (31, 32) situated next to one another in the lateral direction are formed in which the tunnel layer (2) and/or the supply element (3) are deliberately in different forms, so that the tunnel probabilities by virtue of the tunnel layer (2) are different from one another in the different subregions (31, 32).
