Electric field tunable superconductor-semiconductor coupling in Majorana nanowires
Electric field tunable superconductor-semiconductor coupling in Majorana nanowires
We study the effect of external electric fields on superconductor-semiconductor coupling by measuring the electron transport in InSb semiconductor nanowires coupled to an epitaxially grown Al superconductor. We find that the gate voltage induced electric fields can greatly modify the coupling strength, which has consequences for the proximity induced superconducting …
