Abstract
Dielectric barrier discharges (DBDs) are a typical example of non-thermal atmospheric-pressure gas discharges generated in configurations with an insulating (dielectric) material between the electrodes. This work is to provide a better understanding of the breakdown processes and plasma formation, as well as the effect of the shape and configuration of electrodes on the produced plasma parameters, since the choice of electrode materials, geometry, and arrangement can influence plasma parameters such as electron density, electron energy distribution, and plasma temperature; understanding these characteristics helps optimize the plasma for specific applications. Three types of DBD plasma systems were presented in this work by varying the electrode shape and arrangement; the results indicated that electrode shape and configuration play essential roles in determining plasma parameters
Coaxial dielectric barrier discharge in argon excited by repetitive Gaussian pulse voltage is simulated using a 1-D fluid model. This study investigates the influence of voltage amplitude on discharge characteristics and defines a ratio (R) to characterize the correlation between current density and power consumption....

Hollow-cathode discharge (HCD) is widely applied in processes like chemical vapor deposition because its trench structures can enhance ionization and plasma density and promote sputtering. While discharge characteristics have been studied extensively, existing studies on the breakdown phase have predominantly focused o...

To investigate the influence of electrode surface roughness on gas discharge characteristics under micro-gap conditions, direct-current breakdown experiments were carried out in atmospheric air using a nano-positioning system. Breakdown tests were conducted for five metal electrodes over the electrode gap distances fro...
