研究了具有纳米结构边缘的金箔和铝箔作为氮气和环境空气中电晕放电的电极。由于箔边缘附近的场增强，观察到低的起始电压。对于5mm的电极间间距，最低起始电压被确定为在环境空气中为约1.2kV，在氮气中为约1.1kV。这明显小于文献中报告的具有相似电极间距的尖头的值。基于箔的电极尖端生产极其简单，使其成为低成本、低功耗和易于获得的电晕放电技术的候选者。(C)2013 AIP Publishing LLC.
Gold and aluminum foils with nano-structured edges were investigated as electrodes for corona discharges in nitrogen and ambient air. Low onset voltages were observed due to the field enhancement near the edges of the foil. The lowest onset voltage was determined to be about 1.2 kV in ambient air and about 1.1 kV in nitrogen for a 5mm inter-electrode spacing. This is significantly smaller than the values reported in the literature for sharp tips with similar electrode spacing. The foil-based electrode tips are extremely simple to produce, making them candidates for low-cost, low power consumption and easily available corona-discharge technology. (C) 2013 AIP Publishing LLC.
