Effect of dc voltage pulsing on high-vacuum electrical breakdowns near Cu surfaces
Anton Saressalo, Iaroslava Profatilova, William L. Millar +4
Vacuum electrical breakdowns, also known as vacuum arcs, are a limiting factor in many devices that are based on application of high electric fields near their component surfaces.…
Classification of vacuum arc breakdowns in a pulsed DC system
Anton Saressalo, Iaroslava Profatilova, Andreas Kyritsakis +4
Understanding the microscopic phenomena behind vacuum arc ignition and generation is crucial for being able to control the breakdown rate, thus improving the effectiveness of many…
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…
