Kurzfassung:
We present low-temperature magnetotransport measurements characterizing the promising quaternary Bi 1.5 Sb 0.5 Te 1.8 Se 1.2 topological insulator material. The measurements performed on a nano-Hall bar grown by selective-area molecular beam epitaxy revealed pronounced universal conductance fluctuations. It is shown that these fluctuations originate from phase-coherent loops within the topologically protected surface states. Furthermore, the decay of the fluctuation amplitude with increasing temperatures suggests a quasi one-dimensional transport regime.
