    • Effect of amorphization-mediated plasticity on the hydrogen-void interaction in ideal lattices under hydrostatic tension 

      Zhao, Kai; He, Jianying; Ringdalen, Inga Gudem; Zhang, Zhiliang (Peer reviewed; Journal article, 2018)
      A thermodynamic model is derived to study the void nucleation in ideal lattices under hydrostatic tension loading and predicts that the plasticity has to be initiated before homogeneous nucleation of voids. Molecular ...

    • Effect of the native oxide on the Surface Passivation of Si by Al2O3 

      Getz, Michael; Povoli, Marco; Monakhov, Eduard (Peer reviewed; Journal article, 2021)
      The effect of the native silicon oxide layer on the passivation properties of Al2O3 on p-type Si surfaces has been investigated. This was done by comparing effective carrier lifetime, surface saturation current density, ...

    • Electrochemically driven degradation of chemical solution deposited ferroelectric thin-films in humid ambient 

      Dahl-Hansen, Runar Plunnecke; Polfus, Jonathan Marc; Vøllestad, Einar; Akkopru-Akgun, Betul; Denis, Lyndsey; Coleman, Kathleen; Tyholdt, Frode; Trolier-Mckinstry, Susan E; Tybell, Per Thomas Martin (Peer reviewed; Journal article, 2020)
      The ambient humidity significantly accelerates the degradation of lead zirconate titanate (PZT) films in microelectromechanical systems; the cause of such degradation is under debate. Here, it is shown that the degradation ...

    • Enhancement of thermoelectric properties by energy filtering: Theoretical potential and experimental reality in nanostructured ZnSb 

      Berland, Kristian; Song, Xin; Carvalho, Patricia; Persson, Clas; Finstad, Terje; Løvvik, Ole Martin (Journal article; Peer reviewed, 2016)
      Energy filtering has been suggested by many authors as a means to improve thermoelectric properties. The idea is to filter away low-energy charge carriers in order to increase Seebeck coefficient without compromising ...

    • High performance multicrystalline silicon: Grain structure and iron precipitation 

      Autruffe, Antoine; M'hamdi, Mohammed; Schindler, Florian; Heinz, Friedemann D.; Ekstrøm, Kai Erik; Schubert, Martin C.; Di Sabatino Lundberg, Marisa; Stokkan, Gaute (Peer reviewed; Journal article, 2017)
      A study of the spatial occurrence of iron precipitation in a high performance multicrystalline silicon (HPMC-Si) sample is presented. The separated effects of grain-boundaries, sparse intra-granular dislocations, and ...

    • Interfacial characterization of Al-Al thermocompression bonds 

      Malik, Nishant; Carvalho, Patricia; Poppe, Erik; Finstad, Terje (Journal article; Peer reviewed, 2016)
      Interfaces formed by Al-Al thermocompression bonding were studied by the transmission electron microscopy. Si wafer pairs having patterned bonding frames were bonded using Al films deposited on Si or SiO2 as intermediate ...

    • Investigation of veryintenseD3-band emission in multi-crystalline silicon wafers using electron microscopy and hyperspectral photoluminescence imaging 

      Thøgersen, Annett; Jensen, Ingvild Julie Thue; Graff, Joachim Seland; Ringdalen, Inga Gudem; Almeida Carvalho, Patricia; Mehl, Torbjørn; Zhu, Junjie; Burud, Ingunn; Olsen, Espen; Søndenå, Rune (Peer reviewed; Journal article, 2022)
      Defects in high performance multi-crystalline silicon wafers can be detrimental to the lifetime of the solar cell. It is, therefore, important to study and understand the underlying structure and chemical elements present ...

    • Recombination activity of grain boundaries in high-performance multicrystalline Si during solar cell processing 

      Krzysztof, Adamczyk; Søndenå, Rune; Stokkan, Gaute; Looney, Erin; Jensen, Mallory; Lai, Barry; Rinio, Markus; Sabatino, Marisa Di (Journal article; Peer reviewed, 2018)
      In this work, we applied internal quantum efficiency mapping to study the recombination activity of grain boundaries in High Performance Multicrystalline Silicon under different processing conditions. Wafers were divided ...

    • Screening of thermoelectric silicides with atomistic transport calculations 

      Løvvik, Ole Martin; Flage-Larsen, Espen; Skomedal, Gunstein (Peer reviewed; Journal article, 2020)
      More than 1000 crystalline silicide materials have been screened for thermoelectric properties using first-principles atomistic calculations coupled with the semi-classical Boltzmann transport equation. Compounds that ...
