  • Lifetime degradation mechanism in boron-doped Czochralski silicon 
    Voronkov, Vladimir V.; Falster, Robert; Batunina, A.V.; MacDonald, D.; Bothe, Karsten; Schmidt, J. (London : Elsevier Ltd., 2011)
    The recombination centre that emerges in boron- and oxygen-containing silicon was thought to be a complex of a substitutional boron atom Bs and an oxygen dimer O2. However in material co-doped with boron and phosphorus, ...
  • Simultaneous determination of δ11B and B/Ca ratio in marine biogenic carbonates at nanogram level 
    Kaczmarek, Karina; Horn, Ingo; Nehrke, Gernot; Bijma, Jelle (Amsterdam : Elsevier, 2015)
    In this study we introduce a new in situ technique which allows the determination of the boron isotopic composition and B/Ca ratios simultaneously at the nanogram level using a combination of optical emission spectroscopy ...
