Electron-beam Introduction of Heteroatomic Pt-Si Structures in Graphene
Ondrej Dyck, Cheng Zhang, Philip D. Rack +5
Electron-beam (e-beam) manipulation of single dopant atoms in an aberration-corrected scanning transmission electron microscope is emerging as a method for directed atomic motion a…
Towards Automating Structural Discovery in Scanning Transmission Electron Microscopy
Nicole Creange, Ondrej Dyck, Rama K. Vasudevan +2
Scanning transmission electron microscopy (STEM) is now the primary tool for exploring functional materials on the atomic level. Often, features of interest are highly localized in…
Unsupervised Machine Learning Discovery of Chemical and Physical Transformation Pathways from Imaging Data
Sergei V. Kalinin, Ondrej Dyck, Ayana Ghosh +4
We show that unsupervised machine learning can be used to learn physical and chemical transformation pathways from the observational microscopic data, as demonstrated for atomicall…
Exploring order parameters and dynamic processes in disordered systems via variational autoencoders
Sergei V. Kalinin, Ondrej Dyck, Stephen Jesse +1
We suggest and implement an approach for the bottom-up description of systems undergoing large-scale structural changes and chemical transformations from dynamic atomically resolve…
Atomic mechanisms for the Si atom dynamics in graphene: chemical transformations at the edge and in the bulk
Maxim Ziatdinov, Ondrej Dyck, Stephen Jesse +1
Recent advances in scanning transmission electron microscopy (STEM) allow to observe solid-state transformations and reactions in materials induced by thermal stimulus or electron…
Tracking atomic structure evolution during directed electron beam induced Si-atom motion in graphene via deep machine learning
Maxim Ziatdinov, Stephen Jesse, Bobby G. Sumpter +2
Using electron beam manipulation, we enable deterministic motion of individual Si atoms in graphene along predefined trajectories. Structural evolution during the dopant motion was…
