Paper Abstract

A dielectric barrier discharge apparatus with two liquid electrodes and a photoelectric detection system are specially designed to study the photo-electrical characteristic of different patterns. A series of filamentary patterns, in which the filaments can be fixed for a long time, have been generated from filaments moving stochastically by increasing applied voltage. It follows the sequence of square pattern, square superlattice pattern and hexagon pattern. The studies of optical and electrical characteristics, including discharge current, light signals, the voltage drop across discharge gap, transported charges, and Lissajous figures of these different patterns are realized by the photo-electrical detection method. From the light signals and waveforms of current, it is found that the square pattern has two discharge pulses, the square superlattice has three and the hexagon has several pulses in each half cycle of the applied voltage. The voltage drop across discharge gap and transported charges increase with the increasing of applied voltage. The dissipated power obtained by the charge-voltage Lissajous figures also increases with the increasing of applied voltage.
