| 摘 要： | 描述了小空间尺度下一种硅外延平面二极管过流时的实验现象,以电压调控开关的模型解释这种现象。通过电压调控开关模型的二极管间隙间电势变化过程的定性分析可知,由于空间电荷效应,超过或临界空间电荷时,二极管电流有可能呈现振荡特性。通过无限大空间内薄束漂移的时间行为证明了这种振荡存在的可能性。用非线性方程的数学模型对这种现象做了仿真,仿真结果与实验现象相吻合。

| Abstract: | The experiment phenomenon in a small-scale space when a kind of silicon diode is in the over-current state is described and explained through the voltage-regulated switch model. The relaxation oscillation is proved through temporal behavior of the thin-beam drift in a infinite space. Moreover, the simulation made with nonlinear equation mathematical model, which is applicable to chaos, demonstrates that under certain initial normalized current values and parameters, the simulation results are consistent with the experimental phenomena. |
