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…
Ab Initio calculation of field emission from metal surfaces with atomic--scale defects
Heikki Toijala, Kristjan Eimre, Andreas Kyritsakis +2
In this work we combine density functional theory and quantum transport calculations to study the influence of atomic--scale defects on the work function and field emission charact…
Dynamic coupling between particle-in-cell and atomistic simulations
Mihkel Veske, Andreas Kyritsakis, Kyrre Ness Sjobak +3
We propose a method to directly couple molecular dynamics, finite element method and particle-in-cell techniques to simulate metal surface response to high electric fields. We use…
