摘要
针对光导开关产生的非线性电脉冲的实验结果:线性脉冲—延迟—雪崩(不稳定)—锁定(基本稳定),结合物理原理,应用二维器件模拟器MED IC I,对光导开关的数值模拟结果进行了分析讨论;同时,提出了一个自洽的物理机制.结果表明:理论模拟结果与实验结果相比较基本符合,提出的非线性光导开关的物理机制基本上可以解释光导开关在非线性模式下的各种特征,为进一步解决怎样能使输出的电脉冲更稳定提供了一定的理论依据.
This paper analyses the experiment result of nonlinear electrical pulse generated by PCSS＇s： Linear pulse-Delay--Avalanche （unstable） --Lock-on （quasi-steady state） combining with physical principle with the results of numerical simulation of PCSS＇s by two-dimensional （2-D） device simulator MEDICI, and puts forward a self-consistent physical mechanism at the same time. The result presents that the theoretical simulation result is in line with the result of experiment. The presented physical mechanism of the nonlinear PCSS＇s can explain all kinds of its characteristics in nonlinear mode, which provides theoretical support for the resolution of how to make the output electrical pulse more stable.
