    摘要: On an upper side there is a structured output coupling layer with flanks which are aligned at an angle between 60° and 88° with respect to a layer plane and which form boundaries for output coupling areas provided for the emergence of radiation and offset from one another. The output coupling areas are formed as flat truncated cones and can be rippled or zigzagged at the flanks, in order to increase the probability that the radiation produced strikes an outer interface of the output coupling layer more steeply than at a limiting angle of total reflection.

    摘要: An optoelectronic semiconductor chip (1) comprises a radiation passage area (3), a contact metallization (2a) applied to the radiation passage area (3), and a first reflective layer sequence (2b) applied to that surface of the contact metallization (2a) which is remote from the radiation passage area (3). An optoelectronic component comprising such a chip is also specified.

    摘要: In a radiation-emitting optoelectronic semiconductor chip comprising an active layer (3) at least one p-doped layer (9) and a layer sequence (8) comprising a plurality of undoped layers (4, 5, 6, 7), which is arranged between the active layer (3) and the p-doped layer (9) and contains at least a first undoped layer (5) and a second undoped layer (6), the second undoped layer adjoining the first undoped layer (5) and succeeding the first undoped layer (5) as seen from the active layer (3), the first undoped layer (5) and the second undoped layer (6) in each case contain aluminum, the aluminum proportion being greater in the first undoped layer (5) than in the second undoped layer (6). The layer sequence (8) advantageously acts as a diffusion barrier for the dopant of the p-doped layer.

    摘要: An electroluminescent component (1), in particular an LED chip, which has a high external efficiency in conjunction with a simple construction. The electroluminescent component (1) has a substrate (2); a plurality of radiation decoupling elements arranged at a distance next to one another on the substrate (2) and having an active layer stack (7) with an emission zone (8); and a contact element (9) on each radiation decoupling element (4). The contact elements (9), whose width (b′) is dimensioned such that it is less than the width (b) of the radiation decoupling elements (4), are arranged centrally on the radiation decoupling elements (4), and the width (b) of the radiation decoupling elements (4), for a given height (h), is chosen to be so small that a substantial proportion of the light (11) radiated laterally from the emission zone (8) can be decoupled directly through the side areas (12) of the radiation decoupling elements (4).
