Quantized conductance doubling and hard gap in a two-dimensional semiconductor–superconductor heterostructure

Interface transparency between 2D semiconductors and superconductors is a longstanding problem, seriously hindering potential applications. Here, using a new hybrid system, Kjaergaard et al. report quantized conductance doubling and a hard superconducting gap measured via a quantum point contact, in...
