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