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…

The nature of dynamic local order in CH $_{3}$ NH $_{3}$ PbI $_{3}$ and CH $_{3}$ NH $_{3}$ PbBr $_{3}$

Nicholas Weadock, Tyler Sterling, Julian Vigil +12

Hybrid lead halide perovskites (LHPs) are a class of semiconductor with novel properties that are distinctively governed by structural fluctuations. Diffraction experiments sensiti…
