Numerical study of secondary electron emission in a coaxial radio-frequency driven plasma jet at atmospheric pressure
Torben Hemke, Jan Trieschmann, Alexander Wollny +2
In this work we investigate a numerical model of a coaxial RF-driven plasma jet operated at atmospheric pressure. Due to the cylindrical symmetry an adequate 2-D representation of…
Spatially resolved simulation of a radio frequency driven micro atmospheric pressure plasma jet and its effluent
Torben Hemke, Alexander Wollny, Markus Gebhardt +2
Radio frequency driven plasma jets are frequently employed as efficient plasma sources for surface modification and other processes at atmospheric pressure. The radio-frequency dri…
Self-pulsing of a micro thin cathode discharge
Alexander Wollny, Markus Gebhardt, Torben Hemke +2
Microplasmas operated at atmospheric pressure show a number of peculiar dynamic phenomena. One of these phenomena is self-pulsing, which is characterized by intrinsic pulsing behav…
Ionization wave propagation on a micro cavity plasma array
Alexander Wollny, Torben Hemke, Markus Gebhardt +7
Microcavity plasma arrays of inverse pyramidal cavities have been fabricated in p-Si wafers. Each cavity acts as a microscopic dielectric barrier discharge. Operated at atmospheric…
