Polarization characteristics of adatoms self-diffusing on metal surfaces under high electric fields
Ekaterina Baibuz, Andreas Kyritsakis, Ville Jansson +1
Although atomic diffusion on metal surfaces under high electric fields has been studied theoretically and experimentally since the 1970s, its accurate and quantitative theoretical…
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)…
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…
