In this study, we investigate superconducting hybrid nanowires consisting of patterned gates on a two-dimensional heterostructure of InAs and Al. Lateral quantum dots are used as single-level spectrometers to analyze the subgap states and their polarizations in the nanowire. By applying a magnetic field and adjusting the gate voltage, we study the spin and charge polarizations and their changes in the nanowire.
We investigate superconducting hybrid nanowires defined by patterned gates on a two-dimensional het-erostructure of InAs and Al, with lateral quantum dots operating as single-level spectrometers along the side of the nanowire. Applying magnetic field along the wire axis spin splits dot levels, providing spin-resolved spectroscopy. We investigate spin and charge polarizations of subgap states in the nanowire and their evolution with magnetic field and gate voltage.
