The 4D Camera: an 87 kHz direct electron detector for scanning/transmission electron microscopy
Peter Ercius, Ian J. Johnson, Philipp Pelz +19
We describe the development, operation, and application of the 4D Camera -- a 576 by 576 pixel active pixel sensor for scanning/transmission electron microscopy which operates at 8…
Correlative image learning of chemo-mechanics in phase-transforming solids
Haitao D. Deng, Hongbo Zhao, Norman L. Jin +14
Constitutive laws underlie most physical processes in nature. However, learning such equations in heterogeneous solids (e.g., due to phase separation) is challenging. One such rela…
Correlative analysis of structure and chemistry of LixFePO4 platelets using 4D-STEM and X-ray ptychography
L. A. Hughes, Benjamin H. Savitzky, Haitao D. Deng +9
Lithium iron phosphate (LixFePO4), a cathode material used in rechargeable Li-ion batteries, phase separates upon de/lithiation under equilibrium. The interfacial structure and che…
py4DSTEM: a software package for multimodal analysis of four-dimensional scanning transmission electron microscopy datasets
Benjamin H Savitzky, Lauren A Hughes, Steven E Zeltmann +18
Scanning transmission electron microscopy (STEM) allows for imaging, diffraction, and spectroscopy of materials on length scales ranging from microns to atoms. By using a high-spee…
Patterned Probes for High Precision 4D-STEM Bragg Measurements
Steven E Zeltmann, Alexander Müller, Karen C Bustillo +4
Nanoscale strain mapping by four-dimensional scanning transmission electron microscopy (4D-STEM) relies on determining the precise locations of Bragg-scattered electrons in a seque…
