Universal Drift Correction for Multidimensional Scanning Microscopy
Sangjoon Lee, William Millsaps, Dasol Yoon +7
In scanning microscopy, drift causes the specimen to be sampled at positions displaced from the nominal probe positions. This displacement alters the spatial assignment of the reco…
Bend Contour Electron Tomography (BCET): Quantitative strain and topography mapping
Henry G. Bell, Chenhang Xu, Arthur McCray +5
Freestanding thin films of quantum materials naturally develop sub-micrometer, nonuniform strain fields that strongly affect their electronic, magnetic, and structural properties i…
Real-space overlap is not enough: ambiguity in nanobeam iterative ptychography
Stephanie M. Ribet, Mohsen Danaie, Willem P. M. de Kleijne +5
High-resolution iterative ptychography typically relies on a well-aligned, high-convergence-angle electron probe. Here we explore whether it can instead be performed at small conve…
Mapping Order in Semicrystalline Polymers using Machine Learning of Nanobeam Electron Diffraction
Nicholas Marchese, Arthur R. C. McCray, Yael Tsarfati +4
Organic mixed ionic electronic conductors (OMIECs) are a promising class of polymer materials for applications spanning neuromorphic computation to energy efficient electronics and…
Model-free Analysis of Scattering and Imaging Data with Escort-Weighted Shannon Entropy and Divergence Matrices
Jared Coles, Arthur R. C. McCray, Yue Li +9
We demonstrate a model-free data analysis framework that leverages escort-weighted Shannon Entropy and several divergence matrices to detect phase transitions in scattering and ima…
A Gaussian Parameterization for Direct Atomic Structure Identification in Electron Tomography
Nalini M. Singh, Tiffany Chien, Arthur R. C. McCray +2
Atomic electron tomography (AET) enables the determination of 3D atomic structures by acquiring a sequence of 2D tomographic projection measurements of a particle and then computat…
Missing Wedge Inpainting and Joint Alignment in Electron Tomography through Implicit Neural Representations
Cedric Lim, Corneel Casert, Arthur R. C. McCray +4
Electron tomography is a powerful tool for understanding the morphology of materials in three dimensions, but conventional reconstruction algorithms typically suffer from missing-w…
Deep generative priors for robust and efficient electron ptychography
Arthur R. C. McCray, Stephanie M. Ribet, Georgios Varnavides +1
Electron ptychography enables dose-efficient atomic-resolution imaging, but conventional reconstruction algorithms suffer from noise sensitivity, slow convergence, and extensive ma…
Understanding the effect of curvature on the magnetization reversal of three-dimensional nanohelices
John Fullerton, Arthur R. C. McCray, Amanda K. Petford-Long +1
Comprehending the interaction between geometry and magnetism in three-dimensional (3D) nanostructures is of importance to understand the fundamental physics of domain wall (DW) for…
AI-enabled Lorentz microscopy for quantitative imaging of nanoscale magnetic spin textures
Arthur R. C. McCray, Tao Zhou, Saugat Kandel +3
The manipulation and control of nanoscale magnetic spin textures is of rising interest as they are potential foundational units in next-generation computing paradigms. Achieving th…
Thermal Hysteresis Behavior of Skyrmion Lattices in the van der Waals Ferromagnet Fe3GeTe2
Arthur R. C. McCray, Yue Li, Rabindra Basnet +6
Understanding the physics of phase transitions in two-dimensional (2D) systems underpins the research in diverse fields including statistical mechanics, quantum systems, nanomagnet…
Field-Dependent Magnetic Domain Behavior in van der Waals FeGeTe
Yue Li, Rabindra Basnet, Krishna Pandey +6
Two-dimensional magnetic van der Waals (vdW) materials can show a variety of topological nontrivial spin textures, such as Bloch- or Néel-type stripe, skyrmion or bubble domains un…
