When an electron emitting tip is subjected to very high electric fields, plasma forms even
under ultra high vacuum conditions. This phenomenon, known as vacuum arc, causes …

Theoretical models of thermal, field, and thermal-field emission of electrons generally
require the evaluation of the Gamow, or tunneling, factor. A rapid means to do so is …

Electron emission from nanometric size emitters becomes of increasing interest due to its
involvement to sharp electron sources, vacuum breakdown phenomena and various other …

It has been investigated whether explosive electron emission may be the initiating
mechanism of vacuum breakdown in the accelerating structures of TeV linear electron …

We propose a method to directly couple molecular dynamics, the finite element method, and
particle-in-cell techniques to simulate metal surface response to high electric fields. We use …

Due to the miniaturization of microelectromechanical systems, nanoelectromechanical
systems and molecular devices, the problem of vacuum insulation becomes more and more …

Metal vapor vacuum arcs (VAs) are widely used in various fields of industry, such as circuit
breakers, ion sources, electrical thrusters, and deposition systems. VAs usually originate …

During the previous decade, Jensen et al. developed a general analytical model that
successfully describes electron emission from metals both in the field and thermionic …

Understanding the underlying factors responsible for higher-than-anticipated local field
enhancements required to trigger vacuum breakdown on pristine metal surfaces is crucial …

We propose a method for efficiently coupling the finite element method with atomistic
simulations, while using molecular dynamics or kinetic Monte Carlo techniques. Our method …
