LIGHT-EMITTING ASSEMBLY HAVING A SEMICONDUCTOR LAYER SEQUENCE HAVING AN ACTIVE ZONE ON A COLUMNAR STRUCTURE

摘要

The invention relates to a method for producing an assembly, to an array of assemblies and to an assembly (1) having a columnar structure (5), which is arranged having one end on a substrate (2), wherein the structure (5) is covered having a semiconductor layer structure (6) having an active zone (7) for producing electromagnetic radiation, wherein the active zone (7) has a band gap for a radiative recombination, wherein the active zone (7) is designed such that the band gap decreases in the direction of a free end (25) of the structure (5) such that a diffusion of charge carriers in the direction of a free end (25) of the structure (5) and a radiative recombination of charge carrier pairs is supported in the region of the free end (25) of the structure (5).
