  • ORGANIC PHOTODETECTOR FOR THE DETECTION OF INFRARED RADIATION, METHOD FOR THE PRODUCTION THEREOF, AND USE THEREOF
    Publication number: 20100294936
    Abstract: An organic photodetector detects infrared radiation, particularly radiation within the spectral region of over 1100 nm, the so-called imager region. Contrary to the currently known photodetectors, such as the Bolometer, II-VI semiconductor, and quantum well detectors, the photodetector contains semiconducting nano-particles for shifting the range of detection, requires no technical and cost-intensive effort in the production thereof, and may be constructed of flexible substrates by simple printing methods.

  • ORGANIC PHOTODETECTOR HAVING A REDUCED DARK CURRENT
    Publication number: 20100207112
    Abstract: An organic photodetector has a reduced dark current by incorporating an electron blocking layer or barrier layer between the lower electrode and the organic photoactive layer. TA SAM layer is proposed as the material for the barrier layer.

  • Field emission cathode and x-ray tube embodying same
    Patent number: 7778391
    Abstract: A field emission cathode has a field emitter and an extraction grid, and the field emitter and the extraction grid can be moved relative to one another. Such a field emission cathode is highly durable and exhibits a longer lifespan. An x-ray tube has a field emission cathode composed of a field emitter and an extraction grid that can be moved relative to one another. Such an x-ray tube is highly durable and exhibits a longer lifespan.

  • PHOTODETECTOR, FLAT X-RAY DETECTOR AND METHOD FOR PRODUCING THE SAME
    Publication number: 20100148072
    Abstract: A flat organic photodetector has a structured first electrode that forms several sub-electrodes, a second electrode, at least one first organic layer, and a second organic layer. The organic layers are situated between the two electrodes and are structured in conformity with the structuring of the first electrode, so that the two organic layers are subdivided into multiple active regions respectively corresponding to the sub-electrodes of the first electrode. An x-ray detector has such a flat organic photodetector and an x-ray absorbing layer applied thereon.
