      abstract     = {The combination of an ordinary s-type superconductor with
                      three-dimensional topological insulators creates a promising
                      platform for fault-tolerant topological quantum computing
                      circuits based on Majorana braiding. The backbone of the
                      braiding mechanism are three-terminal Josephson junctions.
                      It is crucial to understand the transport in these devices
                      for further use in quantum computing applications. We
                      present low-temperature measurements of topological
                      insulator-based three-terminal Josephson junctions
                      fabricated by a combination of selective-area growth of
                      Bi0.8Sb1.2Te3 and shadow mask evaporation of Nb. This
                      approach allows for the in situ fabrication of Josephson
                      junctions with an exceptional interface quality, important
                      for the study of the proximity-effect. We map out the
                      transport properties of the device as a function of bias
                      currents and prove the coupling of the junctions by the
                      observation of a multiterminal geometry-induced diode
                      effect. We find good agreement of our findings with a
                      resistively and capacitively shunted junction network
                      model.},
