Three-dimensional imaging of buried heterointerfaces
Colum M. O'Leary, Haozhi Sha, Jianhua Zhang +6
We report three-dimensional (3D) structure determination of a twisted hexagonal boron nitride (h-BN) heterointerface from a single-view data set using multislice ptychography. We i…
Deep Learning Coherent Diffractive Imaging
Dillan J. Chang, Colum M. O'Leary, Cong Su +5
We report the development of deep learning coherent electron diffractive imaging at sub-angstrom resolution using convolutional neural networks (CNNs) trained with only simulated d…
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…
