Proximity-induced superconductivity in all-silicon superconductor /normal-metal junctions
Proximity-induced superconductivity in all-silicon superconductor /normal-metal junctions
We have realised laser-doped all-silicon superconducting (S)/ normal metal (N) bilayers of tunable thickness and dopant concentration. We observed a strong reduction of the bilayers critical temperature when increasing the normal metal thickness, a signature of the highly transparent S/N interface associated to the epitaxial sharp laser doping profile. We …
