Nonlocal quasiparticle transport in normal-superconductor-normal (NSN) hybrid structures probes sub-gap states in the proximity region and is especially attractive in the context of Majorana research. Conductance measurement provides only partial information about nonlocal response composed from both electron-like and hole-like quasiparticle excitations. In this work, we show how a nonlocal shot noise measurement delivers a missing puzzle piece in NSN InAs nanowire-based devices. We demonstrate…

This work identifies the Andreev reflection (AR) regime, which gives rise to the effective charge doubling in shot noise measurements, and suggests that this effect is related to a finite thermal conduction of the proximized, superconducting TI owing to a residual density of states at low energies.
