Abstract

We report magneto-transport measurements of quasi-1-dimensional (1D) Al-InAs nanowires produced via etching of a hybrid superconductor-semiconductor two-dimensional electron gas (2DEG). Tunnel spectroscopy measurements above the superconducting gap provide a means of identifying the 1D sub-bands associated with the confined 1D region. Fitting the data to a model that includes the different components of the spin-orbit interaction (SOI) reveals their strength, of interest for evaluating the suitability of superconductor-semiconductor 2DEG for realizing Majorana qubits.
