Development of Streamers in Dielectric-Barrier-Discharge Excimer Lamp

The development of streamers in a dielectric-barrier-discharge (DBD) excimer lamp has been simulated by using a 2-D fluid model. The DBD is composed of streamer and surface discharges, and the surface discharge significantly affected the shape of the discharge-current waveform. The spatial distributions of electron density, electric field, and excimer density showed the dynamics of the streamer developments, and the behavior of streamers in DBD was clarified in detail.
