Abstract: An optoelectronic semiconductor device may include a first semiconductor layer, a second semiconductor layer, first and second current spreading structures, and an insulating intermediate layer. The second semiconductor layer may be arranged over a substrate. The first semiconductor layer may be arranged between the second semiconductor layer and the substrate. The first current spreading structure may be electrically connected to the first semiconductor layer, and the second current spreading structure electrically may be connected to the second semiconductor layer. The insulating intermediate layer may include a dielectric mirror and may be arranged between the second current spreading structure and the second semiconductor layer. The current spreading structures may overlap one another in a plane perpendicular to a main surface of the substrate. The first current spreading structure may be arranged at a larger distance from the first semiconductor layer than the second current spreading structure.

Abstract: An optoelectronic assembly comprises at least two electrical contacts on a surface of an optoelectronic component for supplying electrical energy for generating electromagnetic radiation, and at least two meander-shaped contact lugs, each of which comprises a first and a second section. The first section in each case of the at least two meander-shaped contact lugs is coupled to one of the at least two electrical contacts. The second section in each case of the at least two meander-shaped contact lugs comprises a fastening element which is designed to go into a mechanical linkage to a fiber structure of a carrier and to create an electrical connection to the first section.

Abstract: An optoelectronic semiconductor chip comprises a semiconductor layer sequence and several semiconductor structures having in each case one active region. The active regions may be designed for the emission and/or absorption of electromagnetic radiation. The active regions of different semiconductor structures may not be connected to one another. The semiconductor structures may be designed as a nanorod or a microrod. The semiconductor structures may be embedded in the semiconductor layer sequence.

Abstract: A semiconductor display may include a multiplicity of semiconductor pillars as well as first contact strips and second electrical contact strips. The semiconductor pillars each comprise a semiconductor core of a first conductivity type and a semiconductor shell of a second conductivity type different from the first conductivity type, as well as an active layer between them for radiation generation. The semiconductor pillars each comprise an energization shell which is applied onto the respective semiconductor shell for energization. The semiconductor pillars can be electrically driven independently of one another individually or in small groups by means of the first and second electrical contact strips.

Abstract: The invention relates to an embodiment in which the textile component comprises at least one flexible thread that can be woven. A plurality of semiconductor columns are attached in or on the thread and are configured to generate radiation. Furthermore, a plurality of electrical lines are located in or on the thread, by means of which lines the semiconductor columns are electrically contacted. An average height (H) of the semiconductor columns in a direction transverse to a longitudinal direction (L) of the thread is at most 20% of an average diameter (D) of the thread.
