001053016 520__ $$aCombining s-type superconductors with three-dimensional topological insulators creates a promising platform for fault-tolerant topological quantum circuits based on Majorana braiding. The braiding mechanism is built around a three-terminal Josephson junction. However, implementing this concept requires a deeper understanding of the underlying mechanisms in topological insulator nanoribbon networks equipped with superconducting electrodes. Our devices are fabricated using a combination of selective-area growth of the topological insulator and shadow mask evaporation of the superconductor. Firstly, we investigate nanoribbon kinks and T-junctions of the topological insulator. In kink structures we observed a π-periodic change in conductance depending on the direction of an in-plane magnetic field. We attribute this phenomenon to an orbital effect that leads to the alignment or misalignment of phase-coherent states on the lower and upper surfaces of the kink branches, depending on the orientation of the magnetic field. Next, we measure the transport properties of three-terminal topological insulator-based Josephson junctions and analyze the junctions' cross-coupling. When an out-of-plane magnetic field is applied, a multi-terminal geometry-induced diode effect is observed.
