Abstract
The present invention relates to a light emitting diode (), comprising at least one p-doped structure, a plurality of n-doped zinc-oxide (ZnO) nanowires () arranged on the at least one p-doped structure, thereby forming a plurality of p-n junctions (), an insulating structure () arranged among the plurality of ZnO-nanowires (), to electrically separate the plurality of p-n junctions (), and a transparent conductive layer (), arranged on the at least one insulating structure () and in electrical contact with the plurality of ZnO-nanowires (), to enable application of a voltage over the plurality of p-n junctions (), thereby enabling emission of light. An advantage with the above light emitting diode () is its improved broadband spectral distribution. Furthermore, as ZnO-nanowires () are used, it is possible to achieve a high brightness.
