TBAWe present transport measurements of a system suggested to host Majorana bound state, a one-dimensional semiconductor nanowire with strong spin-orbit coupling and proximitized by a s-wave superconductor. The nanowires were fabricated by selective area growth and probed by three terminals, two normal leads and one superconducting lead. The design combined with lock-in techniques allowed us to measure the full conductance matrix, providing local and non-local characterization of the states in the wire. Furthermore, radio-frequency techniques combined with fast gating enabled the characterization of local-conductances and fast tuning of the devices. For each case, we study the energy dependence of sub-gap states with chemical potential and Zeeman field and develop additional tools to assist the search for Majorana bound states in proximitized SAG nanowires.
