  • Beam extraction using non vacuum electron beam by reduced acceleration voltage 
    Hassel, T.; Klimov, G.; Beniyash, A. (Bristol : Institute of Physics Publishing, 2018)
    One of the disadvantages of the non-vacuum electron beam (NVEB) systems is a high acceleration voltage, which leads to an increase of defence against X-ray radiation. Due to the reduced acceleration voltage. On the one ...
  • Organic-silicon Solar Cells Exceeding 20% Efficiency 
    Zielke, Dimitri; Niehaves, Claudia; Lövenich, Wilfried; Elschner, Andreas; Hörteis, Matthias; Schmidt, Jan (Amsterdam : Elsevier, 2015)
    Aftera briefreview of therecent evolvement oforganic-silicon heterojunction solar cells,we present here our latest measurements of the saturation current densities (J0) and contact resistances (RC) of crystalline silicon ...
  • Photoelectrochemical and theoretical investigations of spinel type ferrites (MxFe3-xO4) for water splitting: A mini-review 
    Taffa, Dereje H.; Dillert, Ralf; Ulpe, Anna C.; Bauerfeind, Katharina C.L.; Bredow, Thomas; Bahnemann, Detlef W.; Wark, Michael (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Solar-assisted water splitting using photoelectrochemical cells (PECs) is one of the promising pathways for the production of hydrogen for renewable energy storage. The nature of the semiconductor material is the primary ...
  • Reduced wear and adhesion forces by laser dispersing of ceramics 
    Nölke, C.; Claußen, S.; Dudziak, S.; Haferkamp, H.; Barcikowski, S. (Amsterdam : Elsevier B.V., 2010)
    Laser dispersing offers a great potential to fabricate layers or tracks with tailored properties threat duce abrasive or adhesive wear at the surface of highly stressed components. Different ceramic powder materials like ...
