Atmospheric-pressure RF plasma jets based on the parallel-plate COST-Jet reference plasma source geometry *Golda J et al 2016 J. Phys. D: Appl. Phys.* **49** 084003) are investigated in He/O2 mixtures under different driving voltage waveforms....
The influence of externally applied homogeneous transverse magnetic fields of up to 200 G on self-organized striations in capacitively coupled radio-frequency CF4 plasmas is investigated using kinetic simulations. The striations are known to...
An atmospheric-pressure surface dielectric barrier discharge in nitrogen–oxygen mixtures is studied under microsecond (ls) and nanosecond (ns) pulsed excitation. Using intensified charge-coupled device imaging and phase-resolved optical emission...
Helium metastable species play a critical role in sustaining radio-frequency (RF) driven micro atmospheric pressure plasma jets through Penning ionization and for the generation of reactive oxygen and nitrogen species (RONS). Their densities are...
Nanosecond and microsecond plasma-in liquid systems are explored to oxidize or regenerate a copper oxide surface in situ to serve as a catalyst for electrochemical CO2 conversion. The plasma excitation generates H2O2 in the liquid, which induces...
This work investigates the transitions between ohmic mode and Penning-Gamma mode in a capacitively coupled radio frequency micro atmospheric pressure plasma jets operated in He/O2 mixtures by comparing phase-resolved optical emission spectroscopy...
Microdischarges formed in bubbles immersed in liquids are of interest for materials synthesis and chemical conversion applications in the frame of plasma-driven electrochemistry. A key challenge associated with controlling such processes is the...
Precise control of ion energy distribution functions (IEDF) is crucial for selectivity as well as control over sputter rate and substrate damage in nanoscale plasma processes. In this work, a low frequency (100 kHz) tailored pulse-wave-shaped bias...
Numerous studies have shown that dielectric barrier discharge (DBD) and DBD-like plasma jets interact with a treated surface in a complex manner. Eroded traces after treatment cannot be explained by conventional plasma-surface interaction theory....
A key to the understanding of mechanisms during plasma electrolytic oxidation (PEO) is the interaction between microdischarges and an amorphous oxide film. The PEO microdischarges, which are randomly distributed on the surface of a treated...
