...When two superconductors are joined with an extremely thin insulating film between them, a current proportional to the sine of the phase difference of the order parameters of the two superconductors flows as electron pairs pass through the insulating film. This phenomenon was theoretically predicted in 1962 by British Brian David Josephson (1940- ) and experimentally confirmed the following year (Josephson was awarded the Nobel Prize in 1973 for this achievement). The Josephson effect is caused by the tunneling effect of electron pairs, which are responsible for superconductivity. ... *Some of the terminology that mentions "Josephson, BD" is listed below.

…きわめて薄い絶縁膜をはさんで二つの超伝導体を接合したとき,電子対が絶縁膜を通り抜けることにより,二つの超伝導体の秩序パラメーターの位相差の正弦に比例する電流が流れる現象。1962年イギリスのジョセフソンBrian David Josephson(1940‐ )によって理論的に予言され,翌年,実験で確かめられた(この業績により,ジョセフソンは1973年度のノーベル賞を受賞)。 ジョセフソン効果は,超伝導の担い手である電子対のトンネル効果によって生ずるものである。… ※「Josephson,B.D.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
