摘要: An electrosurgical apparatus includes an active electrode with a low-work function coating to improve ablation performance. Low-work coatings include compounds of alkali metals and earth metals. Additionally, the may various micro-structures or asperities nano-structures asperities. array carbon nanotubes be aligned secured on electrode. A return comprises high-work suppress electrical discharge activity
