Webbnified” version of the Cooper-pair wavefunctions. Therefore, the values of the coherence length and the Cooper-pair size in conventional superconduc-tors coincide at T=0: ξ GL(0) = ξ(0) = ξ 0, as shown in Fig. 2a. The coherence length (or the Cooper-pair size) ξ 0 determined by the energy gap at zero WebbThe size of a Cooper pair is given by the coherence length which is typically 1000Å (though it can be as small as 30Å in the copper oxides). The space occupied by one pair contains many other pairs, and there is …
