Abstract
We study Andreev reflection in a ballistic one-dimensional channel coupled in parallel to a superconductor via a tunnel barrier of finite length L. The dependence of the low-energy Andreev reflection probability R-A on L reveals the existence of a characteristic length scale xi(N) beyond which R-A(L) is enhanced up to unity despite the low interfacial transparency. The Andreev reflection ...
