Stefan AU - Voigtländer, Bert TI - Distributed Current Injection into a 1D Ballistic Edge Channel PB - arXiv M1 - FZJ-2025-02242 PY - 2025 AB - Quantized charge transport through a 1D ballistic channel was famously explained decades ago by Rolf Landauer, by considering local injection of charge carriers from two contacts at the ends of the 1D channel. With the rise of quantum (spin/anomalous) Hall insulators, i.e., 2D material systems with ballistic 1D edge states along their perimeter, a different geometry has become relevant: The distributed injection of charge carriers from a 2D half-plane with residual conductivity into the 1D edge channel. Here, we generalize Landauer's treatment of ballistic transport to such a setup and identify hallmark signatures that distinguish a ballistic channel from a resistive one.
