Summary

A DETAILED STUDY OF LEAD-LEAD OXIDE-LEAD JUNCTIONS HAS BEEN CARRIED OUT TO STUDY TEMPERATURE DEPENDENCE OF THE JUNCTION RESISTANCE IN THE RANGE 303 TO 77 K (30 TO -196 DEG C). JUNCTIONS ARE CLASSIFIED IN TWO CATEGORIES: ONE WITH RESISTANCE OF ORDER OF 0.5 OHM AND MORE AS HIGH RESISTANCE (HR) AND THOSE BELOW AS LOW RESISTANCE JUNCTIONS (LR). HR JUNCTIONS SHOW LINEAR INCREASE OF RESISTIVITY AS THE TEMPERATURES ARE LOWERED FROM ROOM TEMPERATURE DOWN TO 77 K. HOWEVER LR JUNCTIONS SHOW AN ANOMALOUS BEHAVIOUR WHICH IS DUE TO THE TEMPERATURE VARIATION OF THE FILM RESISTANCE.
