Abstract
One or more embodiments relate to a light-emitting diode and its manufacturing method. The diode includes at least one radial three-dimensional (3D) structure including a core having a first conductivity, and having a wire or pyramidal shape with edges substantially parallel or oblique to the direction z, an active region configured to emit light radiation, the active region including at least one radial part covering the edges of the core, a shell having a second conductivity, the light-emitting diode including a magnetic layer having a polarization along a main direction substantially parallel to the direction z, so as to increase a residence time at the active region of at least one among the first type and the second type of carriers.

A light-emitting diode comprising at least one radial three-dimensional (3D) structure comprising:
- a core having a first conductivity of a first carrier type, the core having a wire or pyramidal shape oriented along a direction z, and having edges substantially parallel or oblique to the direction z,
- an active region configured to emit a light radiation of wavelength k, the active region comprising at least one radial part covering the edges of the core, and
- a shell having a second conductivity of a second carrier type, the shell covering at least the radial part of the active region,
- wherein the light-emitting diode comprises at least one magnetic layer configured to have a polarization along a main direction substantially parallel to the direction z, so as to increase a residence time at the active region of at least one among the first type and the second type of carriers.
