一、超灵敏电磁探测器的工作原理——约瑟夫逊(Jose-phson)效应1973年诺贝尔奖金获得者、英国年青的研究生约瑟夫逊在1962年研究结的隧道时提出,如果两个超导体如图1所示被很薄的绝缘层(5—20埃)分开时,则超导体Ⅰ和超导体Ⅱ之间有位相关联,它导致以超导电子对的形式隧道通过结,超导体Ⅰ和超导体Ⅱ之间不存在隧道电阻这个过程就是超导隧道效应或约瑟夫逊效应。 First, the working principle of ultra-sensitive electromagnetic detectors - Josefonson (Jose-phson) effect 1973 Nobel Prize winner, the British young graduate student Josef Joseph proposed in 1962 when the junction of the tunnel proposed that if the two superconductors shown in Figure 1 is separated by a thin insulating layer (5-20 angstroms), the superconductor I and the superconductor II have a bit correlation that leads to tunneling through the junction, superconductor I and superconductor II in the form of superconductor pairs There is no tunnel resistance between this process is the superconducting tunnel effect or Josephson effect.
