“…Small vari- ations in the microcavity discharge voltage cause large changes in the microcavity discharge current and consequently in the current to the third, external electrode. This method allowed not only the generation of larger atmospheric pressure discharges in noble gases but also in molecular gases, such as air [76] as shown in Figure 26c [77].…”

Abstract. The field of microplasmas gained recognition as a well-defined area of research and application within the larger field of plasma science and technology about 20 years ago. Since then, the activity in microplasma research and applications has continuously increased. A survey of peer reviewed papers on microplasmas published annually shows a steady increase from fewer than 20 papers in 1995 to about 75 in 2005 and more than 150 in 2014. This count excludes papers that deal exclusively with technological applications where the microplasma is used solely as a tool. This topical review aims to provide a snap shot of the current state of microplasma research and applications. Given the rapid proliferation of microplasma applications, the topical review will focus primarily on the status of microplasma science and our understanding of the physics principles that enable microplasma operation. Where appropriate, we will also address microplasma applications, however, we will limit the discussion of microplasma applications to examples where the application is closely tied to the plasma science. No attempt is made to provide a comprehensive and in-depth review of the diverse range of all microplasma applications, except for the inclusion of a few key references to recent reviews of microplasma applications.

“…The n e value in the positive column is consistent with that reported by Mohamed et al . 22 . Apparently, for the discrete discharges with 2.5 mm W g , the calculated n e (5.3 × 10 13 cm −3 ) is in the same order with that obtained by the Stark broadening of H β (6.1 × 10 13 cm −3 ).…”

Scaling up atmospheric pressure glow discharge to large volume is desirable for low-temperature plasma applications. In this paper, an approach to generate a glow discharge in a planar shape with a fairly large volume is proposed in atmospheric pressure air through utilizing a direct-current excited rod array electrode. The planar discharge with a wide gap originates from three discrete discharges with a narrow gap. Based on electrical method and optical emission spectroscopy, it is found that gap voltage increases, while discharge current remains constant with increasing the gap width. Temperature and electron density of the discharge decrease with increasing the gap width.

“…The advantages of operating at atmospheric pressure have led to the development of a variety of low-temperature plasma sources with quite different technical means of generating the plasma as, for example, microwave discharges [3,4], corona discharges [1,5], barrier discharges [6,7], micro-hollow cathode discharges [8,9], and plasma jets [10,11]. Recently, the atmospheric-pressure glow discharges (APGDs) have been considered as the most promising non-equilibrium plasma source for surface treatments [1,6,[12][13][14][15][16].…”

Thin layers of atmospheric-pressure non-equilibrium plasma can be generated by pulse surface corona discharges and surface barrier discharges developing on the treated surfaces or brought into a close contact with the treated surfaces. Plasma sources based on these discharge types have the potential of meeting the basic on-line production requirements in the industry and can be useful for a wide range of surface treatments and deposition processes including continuous treatment of textiles. Comparing with atmospheric pressure glow discharge sources, the potential advantages of these plasma sources include their simplicity, robustness, and capability to process in a wide range of working gases.
