Low-Temperature Detectors

The authors present tunneling results for junctions comprising Mn doped Al films produced by sputter deposition, with Mn concentrations in the range of 0-5000 ppm. Our results for S I S , S I S, and N/I/S junctions demonstrate that Al-Mn alloys can serve both as superconductors with critical temperatures reduced from that of Al and as normal metals. The authors find Al-Mn in this doping range to be otherwise identical to pure Al in terms of its BCS-like tunnel characteristics (for superconductors) and its ability to produce high-quality tunnel barriers.
