How Fast is Your Detector? The Effect of Temporal Response on Image Quality
Tiarnan Mullarkey, Matthew Geever, Jonathan J. P. Peters +3
With increasing interest in high-speed imaging should come an increased interest in the response times of our scanning transmission electron microscope (STEM) detectors. Previous w…
Fast generation of calculated ADF-EDX scattering cross-sections under channelling conditions
Zezhong Zhang, Ivan Lobato, Annick De Backer +2
Advanced materials often consist of multiple elements which are arranged in a complicated structure. Quantitative scanning transmission electron microscopy is useful to determine t…
Procedure for 3D atomic resolution reconstructions using atom-counting and a Bayesian genetic algorithm
Annick De Backer, Sandra Van Aert, Peter D. Nellist +1
We introduce a Bayesian genetic algorithm for reconstructing atomic models of nanoparticles from a single projection using Z-contrast imaging. The number of atoms in a projected at…
Increasing Spatial Fidelity and SNR of 4D-STEM using Multi-frame Data Fusion
Colum M. O'Leary, Benedikt Haas, Christoph T. Koch +2
4D-STEM, in which the 2D diffraction plane is captured for each 2D scan position in the scanning transmission electron microscope (STEM) using a pixelated detector, is complementin…
Direct Imaging of Charge Redistribution due to Bonding at Atomic Resolution via Electron Ptychography
Gerardo T. Martinez, Benjamin X. Shi, Timothy C. Naginey +6
Phase imaging in electron microscopy is sensitive to the local potential, including charge redistribution from bonding. We demonstrate that electron ptychography provides the neces…
The atomic lensing model: new opportunities for atom-by-atom metrology of heterogeneous nanomaterials
K. H. W. van den Bos, L. Janssens, A. De Backer +2
The atomic lensing model has been proposed as a promising method facilitating atom-counting in heterogeneous nanocrystals [KHW van den Bos et. al, Phys. Rev. Lett. 116 (2016) 24610…
