Thermal runaway of metal nano-tips during intense electron emission
A. Kyritsakis, M. Veske, K. Eimre +2
When an electron emitting tip is subjected to very high electric fields, plasma forms even under ultra high vacuum conditions. This phenomenon, known as vacuum arc, causes catastro…
Au nanowire junction breakup through surface atom diffusion
Simon Vigonski, Ville Jansson, Sergei Vlassov +6
Metallic nanowires are known to break into shorter fragments due to the Rayleigh instability mechanism. This process is strongly accelerated at elevated temperatures and can comple…
Simulations of surface stress effects in nanoscale single crystals
Vahur Zadin, Mihkel Veske, Simon Vigonski +5
Onset of vacuum arcing near a metal surface is often associated with nanoscale asperities, which may dynamically appear due to different processes ongoing in the surface and subsur…
Cu self-sputtering MD simulations for 0.1-5 keV ions at elevated temperatures
Tarvo Metspalu, Ville Jansson, Vahur Zadin +4
Self-sputtering of copper under high electric fields is considered to contribute to plasma buildup during a vacuum breakdown event frequently observed near metal surfaces, even in…
Migration barriers for surface diffusion on a rigid lattice: challenges and solutions
Ekaterina Baibuz, Simon Vigonski, Jyri Lahtinen +4
Atomistic rigid lattice Kinetic Monte Carlo is an efficient method for simulating nano-objects and surfaces at timescales much longer than those accessible by molecular dynamics. A…
Dynamic coupling of a finite element solver to large-scale atomistic simulations
Mihkel Veske, Andreas Kyritsakis, Kristjan Eimre +3
We propose a method for efficiently coupling the finite element method with atomistic simulations, while using molecular dynamics or kinetic Monte Carlo techniques. Our method can…
