Nb 조셉슨 접합의 열적 여기현상
Thermal Excitations in Nb Josephson Junctions
초록
We have measured the escape rates of the Nb Josephson junction from its zero-voltage state. The critical current measurements were carried out in repeatedly sweeping the current-voltage characteristics of the junction with a current ramp. From the distribution of the critical current the escape temperature was determined by applying the thermal activation model.
