## Description

- description: Spin-orbit coupling (SOC) provides unique capabilities to control spin
    by moving electrons around or turn electron trajectories by rotating spin. Recently,
    van der Waals interactions with transition metal dichalcogenides was shown to
    induce strong SOCs in graphene, offering great promises to combine large experimental
    flexibility of graphene with unique tuning capabilities of the SOC. Here, we investigate
    both SOC-driven band splitting and electron dynamics in monolayer graphene on
    WSe2 by measuring ballistic transverse magnetic focusing (TMF) effect. We found
    the splitting in the first focusing peak whose evolution in charge density and
    magnetic field is well reproduced by calculations using the SOC strength of ~13
    meV and its absence in the second peak due to interband scattering at the edge.
    Temperature dependence measurement shows the possible suppression of the electron-electron
    scattering in the system. Further, we found that Shubnikov–de Haas oscillations
    exhibit SOC strength of ~3.4 meV, suggesting that it probes different electron
    dynamics, calling for new theory. In addition to providing spectroscopic evidence
    of the spin-orbit-coupled bands, our study demonstrates the possibility to exploit
    various ballistic transport effects in graphene, such as TMF, Veselago lensing,
    and Fabry-Pérot interference, to control or detect spin by turning ballistic electron
    motion.
