Abstract

The detection and investigation of current filaments are reported for diodes made of gold-doped silicon. The investigation was made at room temperature using two methods: a scanning light probe and the sectioning of the contacts. It was found that a filament first appeared in a limited volume and then broadened with increasing voltage across the diode. An inhomogeneous distribution of an impurity in a semiconductor produced a nonuniform broadening of the filament with increasing current, and a complex current—voltage characteristic.
