AB  - The study of the transport properties of quasi one-dimensional topological insulator (TI) nanostructuresunder the application of an in-plane magnetic field is crucial for the later realization oftopological quantum computation building blocks. We present low temperature measurements ofselectively grown TI-Kinks under the application of an in-plane magnetic field. A dependence of theTI-Kink’s resistance on the angle of the in-plane magnetic field is visible in the magnetotransportdata resulting in a π-periodic change of the conductance. This phenomenon originates from anorbital effect, leading to a alignment or misalignment of the phase-coherent states on the bottom andtop surface of the topological insulator. Respectively, the aligned and misaligned states leadto a increased or decreased conductance in the device. The measurement results are supportedtheoretically by the analysis of a surface Rashba-Dirac model and tight-binding simulations of aneffective 3-dimensional mode
