| 20100080068 | MEMORY CELL, AND METHOD FOR STORING DATA - The invention relates, among other things, to a memory cell for storing at least one piece of bit data. Said memory cell comprises at least two electrical terminals and a semiconductor structure with a band curve (EL) that has at least one potential well. The charged state of the potential well with charge carries can be increased by applying a supply voltage (Us=Uspeis) to the two terminals, can be reduced by applying a discharge voltage (Us=Usperr), and can be maintained by applying a maintaining voltage (Us=Ubei), the respective charged state of the potential well defining the piece of bit data of the memory cell. According to the invention, the semiconductor structure has a space charge region (Wn) while the potential well is formed by a semiconductor heterostructure. The semiconductor heterostructure and the space charge region are spatially arranged relative to one another in such a way that the semiconductor heterostructure is located within the space charge region when the maintaining voltage is applied, at the edge of or outside the space charge region when the supply voltage is applied, and within the space charge region when the discharge voltage is applied. | 04-01-2010 |
| 20100074293 | Single-Photon Source and Method for the Production and Operation Thereof - In a method for the production of a single photon source with a given operational performance, the given operational performance for the individual photon source may be fixed by a directed setting of the fine structure gap of the excitonic energy level for at least one quantum dot. The at least one quantum dot is produced with a quantum dot size corresponding to the fine structure gap for setting. | 03-25-2010 |
| 20080233302 | Method and Device for Production of a Three-Dimensional Article - The invention relates to a method and device for production of a three-dimensional article from a material, by means of layered application. According to the invention, a dropwise application is carried out, whereby drops of reaction components are ejected by a nozzle arrangement ( | 09-25-2008 |
| 20080232803 | Hybrid Optical Network and a Method of Routing Data Packets in a Hybrid Optical Network - A hybrid optical network comprising a single channel optical ring network with a plurality of ring nodes and a star subnetwork. The star subnetwork comprises a central wavelength router, a plurality of combiners being connected to input ports of the central wavelength router, and a subset of the ring nodes of the ring network, each node of the subset including a tunable transmitter and a tunable receiver to communicate optical data packets over the star subnetwork. Optical data packets routed between two ring nodes of the subset over the star subnetwork are assigned a specific wavelength that determines the routing of the data packets through the central wavelength router. The invention further regards a method of routing data packets between a source ring node and a destination ring node of a hybrid optical network. | 09-25-2008 |
