Ion-induced secondary electron emission at a target surface is an essential mechanism for laboratory plasmas, i.e. magnetron sputtering discharges. Electron emission, however, is strongly affected by the target condition itself such as oxidation...
Pyrolysis of methane is a promising, new, greenhouse gas-free production method of hydrogen. Here, we present optical emission spectra of a microwave plasma torch operated in an argon methane mixture. Detailed spatial resolution is achieved by...
Nanosecond plasmas in liquids are being used for water treatment, electrolysis or biomedical applications. The exact nature of these very dynamic plasmas and most important their ignition physics are strongly debated. The ignition itself may be...
Nanosecond plasmas in liquids are often generated by applying a short high voltage pulse to an electrode immersed in a liquid for biomedical or environmental applications. The plasmas appear as streamers that propagate through the liquid. The...
Three-dimensional (3D) etching of materials by plasmas is an ultimate challenge in microstructuring applications. A method is proposed to reach a controllable 3D structure by using masks in front of the surface in a plasma etch reactor in...
Magnitude of the electric field of the microwave plasma torch simulated with ansys HFSS
Here, a microplasma channel was investigated. The setup consists of three stacked layers: a magnet, a dielectric foil and two nickel foils that are separated by a 120 μm wide gap. The magnet is grounded while the two nickel foils are powered. The...
Paper Secondary electron emission from magnetron targets, published in IOP PSST 2023. DOI 10.1088/1361-6595/acd57e
Nanosecond plasmas in liquids play an important role in the field of decontamination, electrolysis or plasma medicine. The understanding of these very dynamic plasmas requires information about the temporal variation of species densities and...
Nanosecond plasmas in liquids can initiate chemical processes that are exploited in the elds of water treatment, electrolysis or biomedical applications. The understanding of these chemical processes relies on unraveling the dynamics of the...
