Streamer mode in high gain gallium arsenide photoconductive switches

A streamer mode was proposed based on the gas discharge theory and the theory of optically activated charge domain in high gain gallium arsenide (GaAs) photoconductive switches (PCSS). The paper expounded the whole physical process that from the laser started to illuminate the material to the formation of the streamer. Note the critical conditions in which the streamer form and develop, comparing to the streamer mode in gas. In application of this mode many of the characteristics like transient turn-on and the current filament were explained. Finally indicate that the optically activated charge domain is a kind of special streamer.
