Abstract: Three-dimensional topological insulators form a new material class which is predicted to hold Majorana fermions in the topologically protected surface states. Because of these unique properties they are very interesting candidates for future applications, like topological quantum computing. We investigated the transport properties of three-dimensional topological insulator nanoribbons, which are fabricated by selective-area growth. Weak-antilocalization measurements and conductance fluctuations are employed to gain information on the electron phase-coherence. Furthermore, by measurements in a magnetic field along the nanoribbon axis Aharonov-Bohm type oscillations are observed, indicating the presence of topologically protected surface states. Finally, results on topological insulator-superconductor Josephson junctions are presented.
