  • Assessing the Device-performance Impacts of Structural Defects with TCAD Modeling 
    Needleman, David Berney; Wagner, Hannes; Altermatt, Pietro P.; Buonassisi, Tonio (Amsterdam : Elsevier, 2015)
    Advanced solar cell architectures like passivated emitter and rear (PERC) and heterojunction with intrinsic thin layer (HIT) are increasingly sensitive to bulk recombination. Present device models consider homogeneous bulk ...
  • Chopped sample heating for quantitative profile analysis of low energy electron diffraction spots at high temperatures 
    Kury, P.; Zahl, P.; Horn-von Hoegen, M.; Voges, C.; Frischat, Hannes; Günter, H.-L.; Pfnür, Herbert; Henzler, M. (College Park, MD : American Institute of Physics, 2004)
    Spot profile analysis low energy electron diffraction (SPA-LEED) is one of the most versatile and powerful methods for the determination of the structure and morphology of surfaces even at elevated temperatures. In setups ...
  • Enhanced shot noise in tunneling through a stack of coupled quantum dots 
    Barthold, P.; Hohls, Frank; Maire, Niels; Pierz, Klaus; Haug, Rolf J. (College Park, MD : American Physical Society, 2006)
    We have investigated the noise properties of the tunneling current through vertically coupled self-assembled InAs quantum dots. We observe super-Poissonian shot noise at low temperatures. For increased temperature this ...
