摘要: Abstract The superconducting transition temperature T c of Nb/Cu superlattices has been investigated as a function layer thickness. dependence above 300 A thickness agrees well with proximity effect theory no adjustable parameters. Below A, the data in conjunction current shows that Nb decreases This is interpreted changes electronic density states due to decrease mean-free path.
