  • GaN based light emitters with band-edge aligned carrier blocking layers
    Patent number: 8143614
    Abstract: Band-edge aligned carrier blocking layers are introduced into wurtzite or zinc blend Gallium Nitride based diode laser and LEDs in order to prevent thermionic emission and the overflow of carriers at elevated operating temperatures. These blocking layers are located in the direct vicinity of the active zone of the light emitter, and are designed with material composition such that one of the band-edges of the layers is, either partially or fully, aligned with that of adjacent barrier or waveguide layer. This invention proposes GaN based QW structure with a AlGaN(AsPSb) electron-blocking layer on the p-side of quantum well and (InGa)AlN as hole-blocking layer.

  • AIR GUIDING DEVICE
    Publication number: 20120068498
    Abstract: An air guiding device is arranged in a front end part of a motor vehicle and has an air guiding duct containing a radiator unit through which fresh air flows. A wheel house grille is arranged in the guiding duct downstream of the radiator unit. The wheel house grille has differently positioned air guiding slats for the passage of radiator outlet air. The air guiding slats are positioned so that part of the radiator outlet air is guided to the vehicle outside and a further part of the radiator outlet air can be supplied to the vehicle inside and via a deflecting blade to a wheel brake for cooling. The air guiding slats may also be closed over subregions by means of a facing such that no outlet air can flow through the slats in the subregions.
