Current Mode Second Breakdown.
Abstract
A discussion on current mode second breakdown is given. A computer model is given which shows the voltage-current density characteristic with different injection ratios for the n(+) np(+) diode with reach-through. The model shows that there will always be a negative differential resistance for any injection ratio at high current densities. It is argued, however, that the experimentally observed second breakdown must be explained by a sudden change in injection ratio and not by the change in voltage with any given injection ratio. A discussion of the importance of the base resistance in causing a change in injection ratio is given. Finally an approximate physical model and experimental verification are given. (Author)
