摘要：

A phase-controlled superconducting device, employing an interferometer in solids analogous to the Michelson interferometer, is proposed and its operation is confirmed experimentally. In the device, a Nb-Si boundary is used as a mirror for electron waves in Si, and path-length difference between electron waves is artificially controlled by shifting the actual boundary position due to the superconducting proximity effect. Interference peaks are observed in the differential resistance curves and the energies of these peaks are controlled by gate voltage.
