Direct matter disassembly via electron beam control: Electron-beam-mediated catalytic etching of graphene by nanoparticles
Ondrej Dyck, David Lingerfelt, Songkil Kim +2
We report electron-beam activated motion of a catalytic nanoparticle along a graphene step edge and associated etching of the edge. This approach enables beam-controlled etching of…
Structure retrieval from 4D-STEM: statistical analysis of potential pitfalls in high-dimensional data
Xin Li, Ondrej Dyck, Stephen Jesse +3
Four-dimensional scanning transmission electron microscopy (4D-STEM) is one of the most rapidly growing modes of electron microscopy imaging. The advent of fast pixelated cameras a…
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…
