      abstract     = {Oxidized Si(111) substrates were pre-structured by electron
                      beam lithography and used as a substrate for the selective
                      growth of three-dimensional topological insulators (TI) by
                      molecular beam epitaxy. The patterned holes were filled up
                      by the TI, i.e. Sb2Te3 and Bi2Te3, to form nanodots.
                      Scanning electron microscopy and focused ion beam
                      cross-sectioning was utilized to determine the morphology
                      and depth profile of the nanodots. The magnetotransport
                      measurements revealed universal conductance fluctuations
                      originating from electron interference in phase-coherent
                      loops. We find that these loops are oriented preferentially
                      within the quintuple layers of the TI with only a small
                      perpendicular contribution. Furthermore, we found clear
                      indications of an conductivity anisotropy between different
                      crystal orientations.},
