PtyRANNOSAUR: Ptychography with Robust Artificial Neural Networks Optimized for Sub-Angstrom Accuracy and Ultrafast Reconstruction
Kieran Loehr, Rahim Raja, Xiaochuan Ding +5
We present PtyRANNOSAUR, a data-driven neural network code that reconstructs atomic resolution electron ptychography data in seconds, 10-100x faster than standard methods. PtyRANNO…
3D Mapping of Defects and Moiré Corrugations via Electron Ptychography Atomic Coordinate Retrieval
Jeffrey Huang, Yichao Zhang, Sang hyun Bae +3
Defects and reconstructions in 2D moiré materials cause out-of-plane deformations which strongly modify their electronic properties but are difficult to experimentally access. Here…
Atom-by-atom Imaging of Moiré Phasons using Electron Ptychography
Yichao Zhang, Ballal Ahammed, Sang Hyun Bae +7
Twisted 2D materials exhibit unique vibrational modes called moiré phonons, which arise from the moiré superlattice. Here, we demonstrate atom-by-atom imaging of phasons, an ultras…
Formation of Quasi-Bound States in the Continuum in a Single Deformed Microcavity
Shuai Liu, Bo-Han Wu, Jeffrey Huang +1
Bound states in the continuum (BIC) holds significant promise in manipulating electromagnetic fields and reducing losses in optical structures, leading to advancements in both fund…
Disorder and diffuse scattering in single-chirality (TaSe)I crystals
Jacob A. Christensen, Simon Bettler, Kejian Qu +11
The quasi-one-dimensional chiral compound (TaSe)I has been extensively studied as a prime example of a topological Weyl semimetal. Upon crossing its phase transition temper…
