Abstract
Optoelectronic component and method for producing the same To improve the permeability of a contact layer (6) of a light-emitting diode (1), it is proposed to provide the contact layer (6) with openings (8) through which photons generated in a pn junction (5) can escape. Small spheres, for example of polystyrene, are used to produce the openings (8). FIG. 1
Claims21
An optoelectronic component comprising a radioparent contact layer (6) on a semiconductor surface based on InxAlyGa1−x−yN, where 0≦x≦1, 0≦y≦1 and x+y≦1, characterized in that
- said contact layer (6) comprises a plurality of mutually juxtaposed recesses (8) and in that the thickness of said contact layer (6) is greater than 5 nm and less than 100 nm.
A method for producing a radioparent contact layer (6) on a semiconductor surface of a semiconductor, characterized in that
- said contact layer (6) is patterned by means of a layer of particles (11) that do not cover the semiconductor surface completely, that comprise recesses (8), and that serve as a mask.
