补充资料：`S_1-I-S_2`隧道结（$S_1-I-S_2$tunneljunction）
`S_1-I-S_2`隧道结（$S_1-I-S_2$tunneljunction）
是指两种不同超导体S1和S2间夹有绝缘介质层I的隧道结，其I-V特性曲线如图。
由于S1和S2不同，Δ1(T)和Δ2(T)也不等。图中Vmax=|Δ2-Δ1|/e，Vmax=(Δ1 Δ2)/e，在这两者之间是负阻区，而V≥Vmax时，隧道电流迅速上升并接近N-I-N的情景。由负电阻特性和电流的极大和极小可测定Δ1和Δ2。但在T=0K时，因没有热激发准粒子，所以只有当V≥(Δ1 Δ1)/e时才发生准粒子隧道效应。对S-I-S隧道结，Δ1=Δ2，其单电子隧道效应的I-V特性曲线类同于S-I-N的I-V曲线形状。
