Niobium thin-film point-contact Josephson junction

  • 1. Yokogawa Electric Works, Musashino-shi, Tokyo 180, Japan

Description

A stable, niobium thin-film point-contact Josephson junction can be fabricated using rf magnetron sputtering and electron beam lithography. Constant-voltage steps based on a ac Josephson effect are observed up to a voltage level of 4 mV at 4.2 K when a 9-GHz microwave signal is applied. This voltage level is the highest for any thin-film weak link except for the tunnel junction
