摘要: We study the edge-channel transport of electrons in a high-mobility Si/SiGe two-dimensional electron system quantum Hall regime. By selectively populating spin-resolved edge channels, we observe suppression scattering between two channels with spin-up and spin-down. In contrast, when Zeeman splitting levels is enlarged tilting magnetic field direction, spin orientations both relevant are switched to spin-down, inter-edge-channel strongly promoted. The evident dependence adiabatic an individual feature silicon-based systems, originating from weak spin-orbit interaction.
