Scaling approach toward nano electro-discharge machining: Nanoscale patterning of carbon nanotube forests
We found out an approach to pushing the resolution limit of ?EDM down to the nanometer scale. A scaling effect of electrode size on decreasing working voltage was demonstrated both experimentally and theoretically. Reduction of discharge pulse energy due to the decreasing working voltage was achieved and improved the resolution of ?EDM. Nano-scale structures were fabricated on carbon nanotube forests using reduced size of electrode.
