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…
In situ Imaging of an Anisotropic Layer-by-Layer Phase Transition in Few-Layer MoTe2
Chia-Hao Lee, Huije Ryu, Gillian Nolan +9
Understanding the phase transition mechanisms in two-dimensional (2D) materials is a key to precisely tailor their properties at the nanoscale. Molybdenum ditelluride (MoTe2) exhib…
Leveraging generative adversarial networks to create realistic scanning transmission electron microscopy images
Abid Khan, Chia-Hao Lee, Pinshane Y. Huang +1
The rise of automation and machine learning (ML) in electron microscopy has the potential to revolutionize materials research through autonomous data collection and processing. A s…
Nearly hyperuniform, nonhyperuniform, and antihyperuniform density fluctuations in two-dimensional transition metal dichalcogenides with defects
Duyu Chen, Yu Zheng, Chia-Hao Lee +5
Hyperuniform many-body systems in -dimensional Euclidean space are characterized by completely suppressed (normalized) infinite-wavelength density fluctuations, and appear to be…
Deep Learning Enabled Strain Mapping of Single-Atom Defects in 2D Transition Metal Dichalcogenides with Sub-picometer Precision
Chia-Hao Lee, Abid Khan, Di Luo +9
2D materials offer an ideal platform to study the strain fields induced by individual atomic defects, yet challenges associated with radiation damage have so-far limited electron m…
