摘要： A method and device for slurrying a suspension, the device including a mixing container with an inlet opening configured to introduce the suspension into the mixing container, a distributor element having a collecting container and an outlet arm fastened to the collecting container, and a shaft with a longitudinal axis, with the shaft and the distributor element arranged inside the mixing container, and the distributor element rotatable around the shaft. The collecting container has a collecting opening that permits passage of the suspension from the inlet opening into the distributor element, the outlet arm has an outflow opening that lets the suspension leave the distributor element, and the outlet arm permitting the suspension to flow out of the distributor element, with a flow of the suspension causing a torque on the distributor element so that the torque supports a rotation around the shaft.

摘要： A device for slurrying a suspension and a method for operating such a device are disclosed. In an embodiment a device includes a mixing container with an inlet opening configured to introduce the suspension into the mixing container a distributor element having a collecting container and an outlet arm fastened to the collecting container and a shaft with a longitudinal axis, wherein the shaft and the distributor element are arranged inside the mixing container, wherein the distributor element is mounted so as to be freely rotatable around the shaft, wherein the collecting container comprises a collecting opening configured to pass the suspension from the inlet opening into the distributor element, wherein the outlet arm comprises an outflow opening configured to let the suspension leave the distributor element, and wherein the outlet arm is designed such that the suspension is able to flow out of the distributor element starting from the collecting container via the outlet arm and the outflow opening, a flow of the suspension causing a torque on the distributor element so that the torque supports a rotation around the shaft.

摘要： The invention relates to an optoelectronic semiconductor chip comprising a semiconductor layer sequence with a first semiconductor layer, a second semiconductor layer and an active layer between the first and the second semiconductor layers. The optoelectronic semiconductor chip further comprises a first contact structure with a plurality of first contact pins and a first contact layer for electrically contacting the first semiconductor layer and a second contact structure for electrically contacting the second semiconductor layer. The first semiconductor layer is disposed between the first contact layer and the active layer. The first contact pins are disposed between the first contact layer and the first semiconductor layer and are separated and spaced at a distance from one another in the lateral direction. An electrical connection with an electrical resistance between the first contact layer and the first semiconductor layer is formed by each first contact pin. The first contact pins are selected such that they have different electrical resistances as a result of electrical connections formed by two different first contact pins.

摘要： A semiconductor chip (20) is described comprising a semiconductor layer sequence (10) based on a phosphide compound semiconductor material or arsenide compound semiconductor material wherein the semiconductor layer sequence (10) contains a p-type semiconductor region (4) and an n-type semiconductor region (2). The n-type semiconductor region (2) comprises a superlattice structure (20) for improving current spreading, wherein the superlattice structure (20) has a periodic array of semiconductor layers (21, 22, 23, 24). A period of the superlattice structure (20) has at least one undoped first semiconductor layer (21) and a doped second semiconductor layer (22), wherein an electronic band gap E2 of the doped second semiconductor layer (22) is larger than an electronic band gap E1 of the undoped first semiconductor layer (21).
