Abstract

An investigation on the discharge characteristic of a dielectric barrier discharge (DBD) device was carried out using bare and ZnO-coated alumina dielectric layer in atmospheric pressure air. Highly conductive ZnO film was first deposited on the alumina surface, and the characteristics of the dielectric barrier discharge were examined and compared. Experimental result shows that discharge behavior was definitely improved in the case of ZnO-coated dielectric barrier discharge. Relevant explanation is offered to describe its discharge physics.
- ZnO-coated surface,
- dielectric barrier discharge,
- atmospheric pressure air,
- scanning electron microscope
