    • Defect Engineering in Plasmonic Metal Oxide Nanocrystals 

      Runnerstom, Evan J; Bergerud, Amy; Agrawal, Ankit; Johns, Robert W.; Dahlman, Clayton J.; Singh, Ajay; Selbach, Sverre Magnus; Milliron, Delia J. (Journal article; Peer reviewed, 2016)
      Defects may tend to make crystals interesting but they do not always improve performance. In doped metal oxide nanocrystals with localized surface plasmon resonance (LSPR), aliovalent dopants and oxygen vacancies act as ...

    • Observation of uncompensated bound charges at improper ferroelectric domain walls 

      Schoenherr, Peggy; Shapovalov, Konstantin; Schaab, Jakob; Yan, Zewu; Bourret, Edith; Hentschel, Mario; Stengel, Massimiliano; Fiebig, Manfred; Cano, Andrés; Meier, Dennis (Journal article; Peer reviewed, 2019)
      Low-temperature electrostatic force microscopy (EFM) is used to probe unconventional domain walls in the improper ferroelectric semiconductor Er0.99Ca0.01MnO3 down to cryogenic temperatures. The low-temperature EFM maps ...

    • Solvent-Controlled Charge Storage Mechanisms of Spinel Oxide Electrodes in Mg Organohaloaluminate Electrolytes 

      Wang, Lu; Wang, Zhaohui; Vullum, Per Erik; Selbach, Sverre Magnus; Svensson, Ann Mari; Vullum-Bruer, Fride (Journal article; Peer reviewed, 2017)
      Considering the improved safety, reduced cost, and high volumetric energy density associated with Mg batteries, this technology has distinct advantages for large-scale energy storage compared to other existing battery ...

    • Topological defects in hexagonal manganites - Inner structure and emergent electrostatics 

      Holtz, Megan, E.; Shapovalov, Konstantin; Mundy, Julia; Chang, C. S.; Yan, Zewu; Bourret, Edith; Muller, David A.; Meier, Dennis; Cano, Andrés (Journal article; Peer reviewed, 2017)
      Diverse topological defects arise in hexagonal manganites, such as ferroelectric vortices, as well as neutral and charged domain walls. The topological defects are intriguing because their low symmetry enables unusual ...
