等离子体-表面相互作用的适当理解是优化大气压等离子体射流（APPJ），以适应特定的应用至关重要。在这项研究中，我们主要集中在APPJ与氧化铟锡（ITO）玻璃基板相互作用的界面图案的模式相互转换的行为。通过调节脉冲电压，ITO表面环形界面图形的形成呈现出扩散图形和流光图形两种模式。此外，这两种模式不是独立的，而是通过引入添加剂N2和O2而相互转化。这主要是由于N2+（B）/O（3 p）比值和局域电场分布的差异造成的。这些关于操作模式和它们之间的相互转换的信息提供了对等离子体-表面相互作用过程中的物理化学性质的深入了解。
The appropriate understanding of the plasma–surface interaction is crucial in optimizing the atmospheric pressure plasma jet (APPJ) to suit a particular application. In this study, we mainly focus on the behavior of mode interconversion for interfacial patterns regarding APPJ interacting with a indium tin oxide (ITO) glass substrate. By regulating the pulse voltage, annular interfacial pattern formation on ITO surface displays two types of modes, that is, the diffuse pattern and the streamer pattern. Furthermore, these two modes are not independent and are transformed into each other by introducing additive N2and O2. The reason is mainly attributed to the difference of the N2+(B)/O(3p) ratio and local electric field distribution. This information on the operation mode and interconversion between them provides deep insights into the nature of the physicochemistry during plasma–surface interaction processes.
