Correcting for probe wandering by precession path segmentation
Gregory Nordahl, Lewys Jones, Emil Frang Christiansen +2
Precession electron diffraction has in the past few decades become a powerful technique for structure solving, strain analysis, and orientation mapping, to name a few. One of the b…
Fast Pixelated Detectors in Scanning Transmission Electron Microscopy. Part II: Post Acquisition Data Processing, Visualisation, and Structural Characterisation
Gary W. Paterson, Robert W. H. Webster, Andrew Ross +5
Fast pixelated detectors incorporating direct electron detection (DED) technology are increasingly being regarded as universal detectors for scanning transmission electron microsco…
Evaluation of different rectangular scan strategies for STEM imaging
Abner Velazco, Magnus Nord, Armand Béché +1
STEM imaging is typically performed by raster scanning a focused electron probe over a sample. Here we investigate and compare three different scan patterns, making use of a progra…
Fast Pixelated Detectors in Scanning Transmission Electron Microscopy. Part I: Data Acquisition, Live Processing and Storage
Magnus Nord, Robert W. H. Webster, Kirsty A. Paton +4
The use of fast pixelated detectors and direct electron detection technology is revolutionising many aspects of scanning transmission electron microscopy (STEM). The widespread ado…
Order and Disorder in the Magnetisation of the Chiral Crystal CrNbS
Gary W. Paterson, Tsukasa Koyama, Misako Shinozaki +9
Competing magnetic anisotropies in chiral crystals with Dzyaloshinskii Moriya exchange interactions can give rise to non-trivial chiral topological magnetisation configurations wit…
3D sub-nanoscale imaging of unit cell doubling due to octahedral tilting and cation modulation in strained perovskite thin films
Magnus Nord, Andrew Ross, Damien McGrouther +5
Determining the 3-dimensional crystallography of a material with sub-nanometre resolution is essential to understanding strain effects in epitaxial thin films. A new scanning trans…
Quantitative strain analysis of InAs/GaAs quantum dot materials
Per Erik Vullum, Magnus Nord, Maryam Vatanparast +5
Geometric phase analysis has been applied to high resolution aberration corrected (scanning) transmission electron microscopy images of InAs/GaAs quantum dot (QD) materials. We sho…
Assessing electron beam sensitivity for SrTiO and LaSrMnO using electron energy loss spectroscopy
Magnus Nord, Per Erik Vullum, Ingrid Hallsteinsen +2
Thresholds for beam damage have been assessed for LaSrMnO and SrTiO as a function of electron probe current and exposure time at 80 and 200 kV acceleration…
