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…
Atomistic behavior of metal surfaces under high electric fields
Andreas Kyritsakis, Ekaterina Baibuz, Ville Jansson +1
Combining classical electrodynamics and density functional theory (DFT) calculations, we develop a general and rigorous theoretical framework that describes the energetics of metal…
Adatom diffusion in high electric fields
Ville Jansson, Ekaterina Baibuz, Andreas Kyritsakis +1
Strong electric fields are known to create biased adatom migration on metallic surfaces. We present a Kinetic Monte Carlo model that can simulate adatom migration on a tungsten (W)…
