Effect of dislocations present in the base crystal upon the electrical breakdown characteristics is studied for the case of germanium alloyed p^+-n junctions. Microplasmas are observed at liquid nitrogen temperature. Their number seems to be approximately equal to the number of dislocations traversing the p-n boundary of the sample. Such localized breakdown is considered to be due to large saturation currents and high multiplication factor at these spots where dislocations intersect the junction. The current instability may be explained on the basis of the statistical fluctuation of the saturation currents. As to the origin of the strong electric field intensity in the vicinity of a dislocation, geometrical unevenness of the p-n boundary could be assumed. But this assumption was not successfully verified experimentally.
