Current oscillation mechanism on silicon epitaxial planar diode

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.
