Parallax Depth Sectioning and 3D Reconstruction in 4D-STEM
Desheng Ma, Chia-Hao Lee, Zixiao Shi +2
Three-dimensional (3D) information is encoded in four-dimensional scanning transmission electron microscopy (4D-STEM) through parallax between the virtual images formed at each det…
Three-dimensional imaging of oxygen dopant distribution in SrCuO by electron ptychography
Hongbin Yang, Jinkwon Kim, Desheng Ma +3
Oxygen dopants play a critical role in tuning the properties of cuprate superconductors, yet it is challenging to visualize them at the atomic scale. Here, we use multislice electr…
Anomalous Thermal Conductivity Reversal Driven by a Fluctuating Charge Density Wave
Han Huang, Jinghang Dai, Joyce Christiansen-Salameh +14
For more than a century, the lattice thermal conductivity of crystalline solids has been known to decrease with increasing temperature, as the phonons that carry heat scatter more…
Using Aberrations to Improve Dose-Efficient Tilt-corrected 4D-STEM Imaging
Desheng Ma, David A Muller, Steven E Zeltmann
Tilt-corrected imaging methods in four-dimensional scanning transmission electron microscopy (4D-STEM) have recently emerged as a new class of direct ptychography methods that are…
Electron Ptychography Images Hydrogen Atom Superlattices and 3D Inhomogeneities in Palladium Hydride Nanoparticles
Zixiao Shi, Qihao Li, Himani Mishra +3
When hydrogen atoms occupy interstitial sites in metal lattices, they form metal hydrides (MHx), whose structural and electronic properties can differ significantly from the host m…
Information in 4D-STEM: Where it is, and How to Use it
Desheng Ma, Guanxing Li, David A Muller +1
Contrast transfer mechanisms for electron scattering have been extensively studied in transmission electron microscopy. Here we revisit H. Rose's generalized contrast formalism fro…
Mic-hackathon 2024: Hackathon on Machine Learning for Electron and Scanning Probe Microscopy
Utkarsh Pratiush, Austin Houston, Kamyar Barakati +70
Microscopy is a primary source of information on materials structure and functionality at nanometer and atomic scales. The data generated is often well-structured, enriched with me…
PtyRAD: A High-performance and Flexible Ptychographic Reconstruction Framework with Automatic Differentiation
Chia-Hao Lee, Steven E. Zeltmann, Dasol Yoon +2
Electron ptychography has recently achieved unprecedented resolution, offering valuable insights across diverse material systems, including in three dimensions. However, high-quali…
