摘要
We report a dot-line square super-lattice pattern with surface discharge (DLSSPSD) in a dielectric barrier discharge system and show for the first time that the surface discharge can promote the formation of volume discharge (VD). The pattern consists of three different discharge morphologies, namely, bright spots, dim spots, and bright lines. The spatiotemporal dynamics of the DLSSPSD are studied using an intensified charge-coupled device camera, a photomultiplier, and a high-speed video camera. The results show that the VD located at the dim spots and bright lines is generated on both the rising and falling edges of the voltage. It is found that the high surface charge density transferred by the surface discharge of the bright spots promotes the formation of VD at the dim spots and bright lines.
