    • Bending stability of Cu0.4CrO2 - A transparent p-type conducting oxide for large area flexible electronics 

      Fleischer, Karsten; Shvets, Igor; Caffrey, David; Mullarkey, Daragh; Norton, Emma; Zhussupbekova, A.; Papanastasiou, Dorina T.; Oser, D.; Bellet, D. (2018)
      The current best performing p-type transparent conducting oxides are typically highly crystalline materials, deposited at high temperatures, and hence incompatible with the drive to low cost flexible electronics. We ...

    • Electron trapping by neutral pristine ferroelectric domain walls in BiFeO3 

      Sanvito, Stefano; Körbel, Sabine; Hlinka, Jirka (2018)
      First-principles calculations for pristine neutral ferroelectric domain walls in BiFeO3 reveal that excess electrons are selectively trapped by the domain walls, while holes are only weakly attracted. Such trapped excess ...

    • Magneto-optic Kerr effect in a spin-polarized zero-moment ferrimagnet 

      Fleischer, Karsten; Coey, John; Rode, Karsten; Smith, Christopher; Shvets, Igor; Thiyagarajah, Naganivetha; Lau, Yong-Chang; Betto, Davide; Borisov, Kiril (2018)
      The magneto-optical Kerr effect (MOKE) is often assumed to be proportional to the magnetization of a magnetically ordered metallic sample; in metallic ferrimagnets with chemically distinct sublattices, such as rare-earth ...

    • Nitrogen grain-boundary passivation of In-doped ZnO transparent conducting oxide 

      FLEISCHER, KARSTEN; SHVETS, IGOR; CAFFREY, DAVID; Ali, D.; Butt, M.Z.; Coughlan, C. (2018)
      We have investigated the properties and conduction limitations of spray pyrolysis grown, low-cost transparent conducting oxide ZnO thin films doped with indium. We analyze the optical, electrical, and crystallographic ...
