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 catastrophic surface modifications and constitutes a major limiting factor not only for modern electron sources, but also for many large-scale applications such as particle accelerators, fusion reactors etc. Although vacuum arcs have been studied thoroughly, the physical mechanisms that lead from intense electron emission to…

Mechanism of Spontaneous Surface Modifications on Polycrystalline Cu Due to Electric Fields
TLDR
This paper conducts molecular dynamics simulations of nanocrystalline copper surfaces and shows the possibility of protrusion growth under the stress exerted on the surface by an applied electrostatic field, and establishes a linear relationship between the necessary electrostatic stress for protrusion formation and the temperature of the system.
Direct observation of vacuum arc evolution with nanosecond resolution
TLDR
It is shown evidently that the anode illumination is weaker and plays a minor role in igniting and maintaining the conductive channel, and both the nanosecond-resolution images of vacuum arc evolution and the corresponding theoretical calculations agree that the Conductive channel between the electrodes is built in the form of cathodic plasma long before any significant activity develops in the anodes.
Molecular dynamics simulations of thermal evaporation and critical electric field of copper nanotips
