| 520 | _ | _ | |a Networks of three-dimensional nanoribbons of topological insulators (TI) in combination with superconducting electrodes are promising building blocks for topoelectronic applications and topological quantum computations. In our approach, these structures are fabricated by a dedicated fabrication method that uses selective-area growth in combination with in-situ shadow evaporation of the superconducting electrodes. On single straight TI nanoribbons and TI ring structures, we have found pronounced Aharonov-Bohm oscillations in magnetoresistance, indicating transport via topologically protected surface states [1,2,3]. In three-terminal TI nanoribbon T- and Y-junctions, a dependence of the current on the in-plane magnetic field has been observed, with the current in the surface states being clearly steered toward a preferred output at different magnetic field orientations. The origin of this steering effect is interpreted in terms of orbital effects in combination with spin-momentum locking [4]. In in-situ prepared superconductor-topological insulator nanoribbon Josephson junctions a pronounced supercurrent was observed [5]. For multi-terminal TI hybrid junction the interplay of the Josephson supercurrent in the different branches is investigated. Here, we found a clear coupling in the supercurrent between the different electrodes. Work done in collaboration with: D. Rosenbach, J. Kölzer, G. Behner, E. Zimmermann, J. Teller, A. Rupp, J.
