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…
The Compact Linear ee Collider (CLIC): Physics Potential
P. Roloff, R. Franceschini, U. Schnoor +1
The Compact Linear Collider, CLIC, is a proposed ee collider at the TeV scale whose physics potential ranges from high-precision measurements to extensive direct sensitivit…
Data sets and trained neural networks for Cu migration barriers
Jyri Kimari, Ville Jansson, Simon Vigonski +4
Kinetic Monte Carlo (KMC) is an efficient method for studying diffusion. A limiting factor to the accuracy of KMC is the number of different migration events allowed in the simulat…
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…
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…
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…
Updated baseline for a staged Compact Linear Collider
The CLIC, CLICdp collaborations, : +515
The Compact Linear Collider (CLIC) is a multi-TeV high-luminosity linear e+e- collider under development. For an optimal exploitation of its physics potential, CLIC is foreseen to…
