Mainstream field electron emission (FE) theory—the theory normally used by FE
experimentalists—employs a Sommerfeld-type free-electron model to describe FE from a …

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 …

In field electron emission (FE) studies, interpretation of measured current–voltage
characteristics and extraction of emitter characterization parameters are usually carried out …

We advocate the use of lookup tables in the development of extremely fast and accurate
multiscale models based on the coupling of a quantum-mechanical wave impedance …

Representing field emission data on a Fowler–Nordheim plot is both very common and
strongly not recommended. It leads to a spurious estimation of the emitter parameters …

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 …

Multi-scale and multi-physics simulations are carried out for nano-emitters consisting of FCC
(Al, Cu and Au), BCC (V, Mo and W) and HCP (Ti, Zn and Zr) metals, using hybrid …

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

We performed multiscale-multiphysics simulations for W, Mo and Cu nanotips under high
electric field to investigate their structural evolution and thermal runaway process. The …
