Alongside the search for room-temperature superconductors, physicists are studying how to integrate “supercurrents” into devices made of other materials. To this end, Shlomi Bouscher and colleagues at the Technion – Israel Institute of Technology have demonstrated an efficient way to inject Cooper pairs—the bound electron pairs that carry supercurrents—into a semiconductor heterostructure [1]. The technique could lead to hybrid devices that combine the exotic properties of superconductors with the more familiar ones of semiconductors.
