Claims

C1strongest claim

Proper analysis of the full magnetoresistance data facilitates extraction of the quantum well carrier density, spin-orbit coupling strength, and both transport and quantum scattering times. Most importantly, the extracted scattering times in the 2DEG are impacted by the metal-semiconductor coupling strength allowing us to quickly gain information on proximity-induced superconducting gap without any fabrication or mK measurements.

C2weakest assumption

That the quantum and transport scattering times extracted via standard SdH fitting are quantitatively and directly modulated by the proximity-induced gap in a manner that can be calibrated and interpreted without independent low-temperature gap measurements or additional modeling.

C3one line summary

SdH magnetoresistance analysis in InAs/Al heterostructures extracts 2DEG parameters and estimates proximity gap strength from accessible measurements.
