  • Access to metastable complex ion conductors via mechanosynthesis: Preparation, microstructure and conductivity of (Ba,Sr)LiF3 with inverse perovskite structure 
    Düvel, A.; Wegner, S.; Efimov, K.; Feldhoff, A.; Heitjans, Paul; Wilkening, Martin (Cambridge : Royal Society of Chemistry, 2011)
    Highly metastable Ba1−xSrxLiF3 (0 < x ≤ xmax ≈ 0.4) with an inverse perovskite structure analogous to that of BaLiF3 was synthesized by soft mechanical treatment of BaF2 and LiF together with SrF2 at ambient temperature. ...
  • Advances in the surface passivation of silicon solar cells 
    Schmidt, Jan; Werner, Florian; Veith, Boris; Zielke, Dimitri; Steingrube, S.; Altermatt, Pietro P.; Gatz, Sebastian; Dullweber, Thorsten; Brendel, Rolf (Amsterdam : Elsevier BV, 2012)
    The surface passivation properties of aluminium oxide (Al 2O 3) on crystalline Si are compared with the traditional passivation system of silicon nitride (SiN x). It is shown that Al 2O 3 has fundamental advantages over ...
  • Carrier-envelope offset frequency stabilization of a thin-disk laser oscillator via depletion modulation 
    Andrade, José R.C.; Modsching, Norbert; Tajalli, Ayhan; Dietrich, Christian M.; Kleinert, Sven; Placzek, Fabian; Kreipe, Bernhard; Schilt, Stephane; Wittwer, Valentin J.; Südmeyer, Thomas; Morgner, Uwe (Piscataway : Institute of Electrical and Electronics Engineers, 2020)
    We present a novel concept for the stabilization of the carrier-envelope offset (CEO) frequency of femtosecond pulse trains from thin-disk laser oscillators by exploiting gain depletion modulation in the active gain region. ...
  • Ultrafast Feed Drilling of Carbon Fiber-Reinforced Thermoplastics 
    Kakinuma, Yasuhiro; Ishida, Takuki; Koike, Ryo; Klemme, Heiner; Denkena, Berend; Aoyama, Tojiro (Amsterdam : Elsevier, 2015)
    Carbon fiber-reinforced thermoplastics (CFRTP) are just beginning to be utilized for various applications such as aerospace, automobiles, and sporting goods in place of CFRPs, and the demand for through-hole drilling of ...
  • Ultrafast polychromatic ionization of dielectric solids 
    Jürgens, P.; Jupé, M.; Gyamfi, M.; Ristau, Detlev (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    The modeling of the laser-induced damage processes can be divided into thermal and electronic processes. Especially, electronic damage seems to be well understood. In corresponding models, the damage threshold is linked ...
