摘要
We present results of a novel punch-through diode structure which uses a thin SiGe emitter to effectively suppress impact-ionisation-related (BVce0) effects that typically start to dominate the electrical characteristics of conventional punch-through devices at voltages above 2.5-3.0 V, resulting in the occurrence of negative resistances (snap-back) and severely limiting the application range.
