Alloyed germaniump‐njunctions of 0.1 to 0.2 mm diameter or less have been alloyed upon crystals of roughly ten times greater linear dimensions such that when these units are suitably electrolytically etched, ring formations (both scattered rings and tracks of overlapping rings) occur on the crystal faces in the neighborhoods of the junctions. Best current evidence indicates that the observed effects are etch produced. An explanation of this is given in terms of the action of bubbles accompanying the etching procedure.
