Type: article

Abstract: Cryogenic Hybrid Superconducting Electronics In article 2416957, Alessandro Paghi and co-workers propose the InAs-on-Insulator (InAsOI), a new platform for developing superconducting electronics. An epilayer of semiconducting InAs with different electron densities is grown onto a cryogenic insulating InAlAs metamorphic buffer, used to decouple adjacent devices electrically. Josephson junctions with a high supercurrent density are fabricated employing Al as a superconductor and InAsOI with different electron densities.
