Field-Enhanced Transport Processes in the Gas Discharge System With Porous Zeolite

The pressure-driven charge transport processes in microdischarges with a nanoporous zeolite cathode (ZC) are examined according to enhanced effect of electric field. The distributed resistance of the ZC and the impact of the ionizing component of the plasma on the control of the stable operation of a gas discharge electronic device at atmospheric pressure (AP) are investigated for the first time. The contribution of charge carriers in conductivity varied in a wide pressure range up to AP air microplasmas in postbreakdown mode is discussed. The results show that the ionic transport predominated in low electric field while electronic transport predominated in the opposite conditions. Moreover, uniform gas discharge light emission inside the ZCs develops from the surface and can be generated in air up to AP.
