      abstract     = {Topological surface states of three-dimensional topological
                      insulator nanoribbons and their distinct magnetoconductance
                      properties are promising for topoelectronic applications and
                      topological quantum computation. A crucial building block
                      for nanoribbon-based circuits are three-terminal junctions.
                      While the transport of topological surface states on a
                      planar boundary is not directly affected by an in-plane
                      magnetic field, the orbital effect cannot be neglected when
                      the surface states are confined to the boundary of a
                      nanoribbon geometry.Here, we report on the magnetotransport
                      properties of such three-terminal junctions. We observe a
                      dependence of the current on the in-plane magnetic field,
                      with a distinct steeringpattern of the surface state current
                      towards a preferred output terminal for different magnetic
                      field orientations. We demonstrate that this steering effect
                      originates from the orbital effect, trapping the
                      phase-coherent surface states in the different legs of the
                      junction on opposite sides of the nanoribbon and breaking
                      the left-right symmetry of the transmission across the
                      junction. The reported magnetotransport properties
                      demonstrate that an in-plane magnetic field is not only
                      relevant but also very useful for the characterization and
                      manipulation oftransport in three-dimensional topological
                      insulator nanoribbon-based junctions and circuits, acting as
                      a topoelectric current switch.},
