Abstract
A semiconducting structure configured to emit electromagnetic radiation. The structure includes a first zone and a second zone with first and second types of conductivities respectively opposite to each other, the first and second zones being connected to each other to form a semiconducting junction. The first zone includes at least a first and a second part, the first and the second parts being separated from each other by an intermediate layer, as a spreading layer, extending approximately parallel to a junction plane along a major part of the junction. The spreading layer can cause spreading of carriers in the plane of the spreading layer.
