Giant Proximity Effect in Cuprate Superconductors. Bozovic, I., Logvenov, G., Verhoeven, M. A. J., Caputo, P., Goldobin, E., & Beasley, M. R. Phys. Rev. Lett., 93(15):157002, American Physical Society, 2004.

Using an advanced molecular beam epitaxy system, we have reproducibly synthesized atomically smooth films of high-temperature superconductors and uniform trilayer junctions with virtually perfect interfaces. We found that supercurrent runs through very thick barriers. We can rule out pinholes and microshorts; this “giant proximity effect” (GPE) is intrinsic. It defies the conventional explanation; it might originate in resonant tunneling through pair states in an almost-superconducting barrier. GPE may also be significant for superconducting electronics, since thick barriers are easier to fabricate.
