A computational study of positive streamers interacting with dielectrics
Xiaoran Li, Anbang Sun, Guanjun Zhang +1
We use numerical simulations to study the dynamics of surface discharges, which are common in high-voltage engineering. We simulate positive streamer discharges that propagate towa…

Intense boundary emission destroys normal radio-frequency plasma sheath
Guang-Yu Sun, An-Bang Sun, Guan-Jun Zhang
Plasma sheath is the non-neutral space charge region that isolates bulk plasma from boundary. Radio-frequency (RF) sheathes are formed when applying RF voltage to electrodes. Gener…

On the role of secondary electron emission in capacitively coupled radio frequency plasma sheath: a theoretical ground
Guang-Yu Sun, Han-Wei Li, An-Bang Sun +5
We propose a theoretical ground for emissive capacitively coupled radio-frequency plasma sheath under low pressure. The rf sheath is assumed to be collisionless, and oscillates wit…
