Abstract:

Dayem bridge Josephson junctions were successfully fabricated for the first time from sputtered thin films of high-T sub c Nb3Ge. Microwave induced current steps were observed in the I-V characteristic of one of these junctions at a frequency of 10 GHz at temperatures between 20.9 and 21.0K. This junction was fabricated by a mechanical scribing technique instead of sputter etching. Sputter etched junctions also exhibited Josephson steps, but only at much lower temperatures, due to a depression of T sub c by the sputter etching process.
