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…
E-beam manipulation of Si atoms on graphene edges with aberration-corrected STEM
Ondrej Dyck, Songkil Kim, Sergei V. Kalinin +1
The burgeoning field of atomic level material control holds great promise for future breakthroughs in quantum and memristive device manufacture and fundamental studies of atomic-sc…
Assembling Di- and Multiatomic Si Clusters in Graphene via Electron Beam Manipulation
Ondrej Dyck, Songkil Kim, Elisa Jimenez-Izal +3
We demonstrate assembly of di-, tri- and tetrameric Si clusters on the graphene surface using sub-atomically focused electron beam of a scanning transmission electron microscope. H…
Mitigating E-beam-induced Hydrocarbon Deposition on Graphene for Atomic-Scale Scanning Transmission Electron Microscopy Studies
Ondrej Dyck, Songkil Kim, Sergei V. Kalinin +1
CVD grown graphene used in (scanning) transmission electron microscopy ((S)TEM) studies must undergo a careful transfer of the one-atom-thick membrane from the growth surface (typi…
Single atom manipulation and control in a scanning transmission electron microscope
Ondrej Dyck, Songkil Kim, Sergei V. Kalinin +1
We demonstrate that the sub-atomically focused beam of a scanning transmission electron microscope (STEM) can be used to controllably manipulate individual dopant atoms in a 2D gra…
Engineering the thermal conductivity along an individual silicon nanowire by selective helium ion irradiation
Yunshan Zhao, Dan Liu, Jie Chen +10
The ability to engineer the thermal conductivity of materials allows us to control the flow of heat and derive novel functionalities such as thermal rectification, thermal switchin…
