Growth mechanism for nanotips in high electric fields
Ville Jansson, Ekaterina Baibuz, Andreas Kyritsakis +5
In this work we show using atomistic simulations that the biased diffusion in high electric field gradients creates a mechanism whereby nanotips may start growing from small surfac…
Tungsten migration energy barriers for surface diffusion: a parameterization for KMC simulations
Ville Jansson, Andreas Kyritsakis, Simon Vigonski +4
We have calculated the migration barriers for surface diffusion on Tungsten. Our results form a self-sufficient parameterization for Kinetic Monte Carlo simulations of arbitrarily…
Molecular dynamics simulations of surface modification formations on polycrystalline Cu under high electric fields
Kristian Kuppart, Simon Vigonski, Alvo Aabloo +2
Vacuum breakdowns in particle accelerators and other devices operating at high electric fields is a common problem in the operation of these devices. It has been proposed that the…
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…
