Coupled simulation of plasma-surface interactions during early stages of vacuum arcing
Roni Koitermaa, Andreas Kyritsakis, Tauno Tiirats +2
We describe fully coupled simulations that bridge atomistic cathode dynamics and plasma formation during the earliest stages of vacuum arcing. The model combines molecular dynamics…
Fundamentals of Vacuum Breakdown in High-Field Systems
Walter Wuensch, Sergio Calatroni, Flyura Djurabekova +2
This review consolidates experimental, theoretical, and simulation work examining the behavior of high-field devices and the fundamental process of vacuum arc initiation, commonly…
Influence of an external static magnetic field on prebreakdown electron emission and heating
Roni Koitermaa, Marzhan Toktaganova, Andreas Kyritsakis +4
High magnetic fields can increase the occurrence of vacuum arcing, suggesting that both electric and magnetic fields can play a role in the vacuum arcing process. The mechanism of…
Towards 4D modelisation of thermal-field emission from semiconductors
Salvador Barranco Cárceles, Aquila Mavalankar, Veronika Zadin +2
The theoretical picture of thermal field-emission (TFE) from semiconductors has been limited to 1D and 2D models. This can be attributed to the complex and interdependent phenomena…
Theory and computation of thermal-field emission from semiconductors
Salvador Barranco Cárceles, Veronika Zadin, Aquila Mavalankar +2
Semiconducting field emitters present some interesting features (e.g.; self-limited electron emission) for both scientific interest and industrial applications. The analysis of exp…
