Electron cascades and secondary electron emission in graphene under energetic ion irradiation
Henrique Vázquez, Alina Kononov, Andreas Kyritsakis +3
Highly energetic ions traversing a two-dimensional material such as graphene produce strong electronic excitations. Electrons excited to energy states above the work function can g…
General scaling laws of space charge effects in field emission
Andreas Kyritsakis, Mihkel Veske, Flyura Djurabekova
The characteristics of field electron and ion emission change when the space charge formed by the emitted charge is sufficient to suppress the extracting electric field. This pheno…
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.…
