Abstract

An experimental study is made of filamentary impact ionization breakdown observed in germanium doped with both group III and group V elements at liquid helium temperature. The approximate size of the filament at various current values after ionization is estimated from the measurement of voltage-current characteristics of small cross section bars with high current pulses. Measurements are also made with cylindrical ``tecnetron'' structures in which the conduction channel can be reduced to very small areas by reverse bias of a ring-shaped p-n junction alloyed around a small cylindrical bar. Results of the two experiments are consistent. Near the lowest current value at which ionization can be sustained (about 40 μa), the approximate filament diameter is 10−3 cm.
