A plastic response due to dislocation activity under intense electric fields is proposed as a source of breakdown. A model is formulated based on stochastic multiplication and arrest under the stress generated by the field. A critical transition in the dislocation population is suggested as the cause of protrusion formation leading to subsequent arcing. The model is studied using Monte Carlo simulations and theoretical analysis, yielding a simplified dependence of the breakdown rates on the electric field. These agree with experimental observations of field and temperature breakdown dependencies.

强电场下击穿形核的随机模型

提出了由于强电场下位错活动引起的塑性响应作为击穿的来源。在现场产生的应力作用下，基于随机乘积和停滞建立模型。建议在位错族群中发生临界转变，作为形成突起的原因，从而导致随后产生电弧。使用蒙特卡洛模拟和理论分析对模型进行了研究，从而简化了击穿速率对电场的依赖性。这些与对场和温度击穿相关性的实验观察一致。
