• Atomic-scale 3D imaging of individual dopant atoms in an oxide semiconductor 

      Hunnestad, Kasper Aas; Hatzoglou, Constantinos; Zeeshan, Muhammad; Vullum, Per Erik; Yan, Zewu; Bourret, Edith; Van Helvoort, Antonius; Selbach, Sverre Magnus; Meier, Dennis (Peer reviewed; Journal article, 2022)
      The physical properties of semiconductors are controlled by chemical doping. In oxide semiconductors, small variations in the density of dopant atoms can completely change the local electric and magnetic responses caused ...
    • Effect of pulse-current-based protocols on the lithium dendrite formation and evolution in all-solid-state batteries 

      Reisecker, V.; Flatscher, Florian; Porz, Lukas; Fincher, C.; Todt, J.; Hanghofer, I.; Hennige, V.; Linares-Moreau, M.; Falcaro, P.; Ganschow, S.; Wenner, Sigurd; Chiang, Y.-M.; Keckes, J.; Fleig, J.; Rettenwander, Daniel (Peer reviewed; Journal article, 2023)
      Understanding the cause of lithium dendrites formation and propagation is essential for developing practical all-solid-state batteries. Li dendrites are associated with mechanical stress accumulation and can cause cell ...
    • Freezing solute atoms in nanograined aluminum alloys via high-density vacancies 

      Wu, Shenghua; Søreide, Hanne-Sofie; Li, Chunan; Liu, gang; Li, Yanjun; Roven, Hans Jørgen; Sun, Jun (Peer reviewed; Journal article, 2022)
      Low-temperature decomposition of supersaturated solid solution into unfavorable intergranular precipitates is a long-standing bottleneck limiting the practical applications of nanograined aluminum alloys that are prepared ...
    • Interstitial oxygen as a source of p-type conductivity in hexagonal manganites 

      Skjærvø, Sandra Helen; Tjønneland Wefring, Espen; Nesdal, Silje K.; Gaukås, Nikolai Helth; Olsen, Gerhard Henning; Glaum, Julia; Tybell, Per Thomas Martin; Selbach, Sverre Magnus (Journal article; Peer reviewed, 2016)
      Hexagonal manganites, h-RMnO3 (R=Sc, Y, Ho–Lu), have been intensively studied for their multiferroic properties, magnetoelectric coupling, topological defects and electrically conducting domain walls. Although point defects ...
    • Local dynamics of topological magnetic defects in the itinerant helimagnet FeGe 

      Dussaux, Antoine; Schoenherr, Peggy; Koumpouras, Konstantinos; Chico, Jonathan; Chang, Kevin; Lorenzelli, Luca; Kanazawa, Naoya; Tokura, Yoshinori; Garst, Markus; Bergman, Anders; Degen, Christian L.; Meier, Dennis (Journal article; Peer reviewed, 2016)
      Chiral magnetic interactions induce complex spin textures including helical and conical spin spirals, as well as particle-like objects such as magnetic skyrmions and merons. These spin textures are the basis for innovative ...
    • Piezoresponse force microscopy and nanoferroic phenomena 

      Gruverman, Alexei; Alexe, Marin; Meier, Dennis (Journal article; Peer reviewed, 2019)
      Since its inception more than 25 years ago, Piezoresponse Force Microscopy (PFM) has become one of the mainstream techniques in the field of nanoferroic materials. This review describes the evolution of PFM from an imaging ...
