대기압 플라즈마 발생용 마이크로 전극 제작 및 저전압 동작 특성

Abstract

- A microstructure array has been proposed for micro plasma generation using electroplating and double exposed process. A stable atmospheric plasma has been generated at a low voltage by utilizing the micro electrode gap. Self-aligned microstructure can provide uniform electrode overlap with precisely controlled gap between the electrodes. The proposed structure allows for triode operation, which can expand the generated plasma over a large area by applying a lateral electric field. Electrical characteristics of the micro triode confirm the large numbers of the plasma ions are drifted to the secondary cathode by the lateral electrical field.
