      abstract     = {We succeeded in the fabrication of topological insulator
                      (Bi0.57Sb0.43)2Te3 Hall bars as well as nanoribbons by means
                      of selective-area growth using molecular beam epitaxy. By
                      performing magnetotransport measurements at low temperatures
                      information on the phase-coherence of the electrons is
                      gained by analyzing the weak-antilocalization effect.
                      Furthermore, from measurements on nanoribbons at different
                      magnetic field tilt angles an angular dependence of the
                      phase-coherence length is extracted, which is attributed to
                      transport anisotropy and geometrical factors. For the
                      nanoribbon structures universal conductance fluctuations
                      were observed. By performing a Fourier transform of the
                      fluctuation pattern a series of distinct phase-coherent
                      closed-loop trajectories are identified. The corresponding
                      enclosed areas can be explained in terms of nanoribbon
                      dimensions and phase-coherence length. In addition, from
                      measurements at different magnetic field tilt angles we can
                      deduce that the area enclosed by the loops are predominately
                      oriented parallel to the quintuple layers.},
