Properties of MgAl2O4 doped alumina barrier layers for dielectric barrier discharge

“…This increase indicated different electrical properties of samples with spinel content between 10-30 vol.%. Higher ϵ r could increase the alternating current (AC) conductivity σ AC = ϵ 0 ϵ r Dω, which could cause differences in filament localization and plasma properties [28,29], and influence ignition voltage as well. The origin of the peak remained unclear and this behaviour suggested another crucial material-dependent parameter affecting behaviour of plasma discharge.…”

Optical and electrical analysis of a temperature-dependent mode transition of a helium cryoplasma

“…However, it is believed that the use of two nitrogen spectra, the SPS of a nitrogen molecule and the first negative system (FNS) of a nitrogen molecular ion, is a simple and useful method for evaluating the behavior of atmospheric pressure plasmas. Information on the SPS of N 2 and the FNS of N + 2 was given in detail in previous studies [38,39], and the relative intensity of these two spectra was considered for evaluating changes in plasma properties in previous studies [36,[40][41][42]. This method can generally be applied to the analysis of atmospheric pressure plasmas, because a small amount of nitrogen gas from air remains in the discharge chamber under the steady-state condition when using a gas flow at atmospheric pressure.…”

Temperature-dependent transition of discharge pattern of He/air cryoplasma

“…At this stage, a possible mechanism is that this tendency may correspond to the phase transition of water vapor. 16 This phenomenon prevents the ignition of consecutive microdischarges at the surrounding location from initial ones. 13 Therefore, water clusters as impurities in air may have been adsorbed on the glass surface.…”

“…Liquid water can be supercooled under atmo-spheric pressure down to almost 230 K, but it is also possible to observe liquid water below the supercooling limit in the case of the evaporative cooling of small clusters. 16 In particular, by magnifying each microdischarge at 190 K in Fig. After water molecules were adsorbed on the glass surface from approximately 230 K, the surface conductivity of the glass surface appeared to increase because the surface conductivity in solid is proportional to the density of the adsorbed water vapor molecules.…”
