    • Atomap - Automated Analysis of Atomic Resolution STEM Images 

      Nord, Magnus Kristofer; Vullum, Per Erik; MacLaren, I; Tybell, Per Thomas Martin; Holmestad, Randi (Journal article, 2017)
      Atomic resolution scanning transmission electron microscopy (STEM) data contain a large amount of information about the structure of a crystalline material. Often, this information is hard to extract, due to the large ...

    • Atomap: a new software tool for the automated analysis of atomic resolution images using two-dimensional Gaussian fitting 

      Nord, Magnus Kristofer; Vullum, Per Erik; MacLaren, Ian; Tybell, Per Thomas Martin; Holmestad, Randi (Journal article; Peer reviewed, 2017)
      Scanning transmission electron microscopy (STEM) data with atomic resolution can contain a large amount of information about the structure of a crystalline material. Often, this information is hard to extract, due to the ...

    • Effect of polar (111)-oriented SrTiO3 on initial perovskite growth 

      Hallsteinsen, Ingrid; Nord, Magnus Kristofer; Bolstad, Torstein; Vullum, Per Erik; Boschker, Jos Emiel; Longo, Paulo; Takahashi, Ryota; Holmestad, Randi; Lippmaa, Mikk; Tybell, Per Thomas Martin (Journal article, 2016)
      In crystalline thin film growth a prerequisite is substrate surfaces with a stable and uniform structure and chemical composition. Various substrate treatments were used to obtain atomically smooth, step-and-terrace ...

    • In-plane structural order of domain engineered La0.7Sr0.3MnO3 thin films 

      Boschker, Jos Emiel; Monsen, Åsmund Fløystad; Nord, Magnus Kristofer; Mathieu, Roland; Grepstad, Jostein; Holmestad, Randi; Wahlström, Erik; Tybell, Thomas (Journal article, 2013)
      We present a detailed structural study of tensile-strained La0.7Sr0.3MnO3 thin films. We use the substrate miscut to control the number of rhombohedral variants in the films and study the in-plane order and structural ...

    • Magnetic domain configuration of (111)-oriented LaFeO3 epitaxial thin films 

      Hallsteinsen, Ingrid; Moreau, Magnus; Chopdekar, R.V.; Christiansen, Emil; Nord, Magnus Kristofer; Vullum, Per Erik; Grepstad, Jostein; Holmestad, Randi; Selbach, Sverre Magnus; Scholl, A; Arenholz, E; Folven, Erik; Tybell, Per Thomas Martin (Journal article; Peer reviewed, 2017)
      In antiferromagnetic spintronics control of the domains and corresponding spin axis orientation is crucial for devices. Here we investigate the antiferromagnetic axis in (111)-oriented LaFeO3/SrTiO3, which is coupled to ...

    • Quantitative strain analysis of InAs/GaAs quantum dot materials 

      Vullum, Per Erik; Nord, Magnus Kristofer; Vatanparast, Maryam; Thomassen, Sedsel Fretheim; Boothroyd, Chris; Holmestad, Randi; Fimland, Bjørn-Ove; Reenaas, Turid Worren (Journal article; Peer reviewed, 2017)
      Geometric phase analysis has been applied to high resolution aberration corrected (scanning) transmission electron microscopy images of InAs/GaAs quantum dot (QD) materials. We show quantitatively how the lattice mismatch ...

    • Structural investigation of epitaxial LaFeO3 thin films on (111) oriented SrTiO3 by transmission electron microscopy 

      Christiansen, Emil; Nord, Magnus Kristofer; Hallsteinsen, Ingrid; Vullum, Per Erik; Tybell, Per Thomas Martin; Holmestad, Randi (Journal article; Peer reviewed, 2015)
      We report on structural domains in LaFeO3 epitaxial thin films on (111) oriented SrTiO3 observed by transmission electron microscopy using low magnification dark field imaging and high resolution transmission electron ...
