## Description

- description: We report that the spin vector of photoelectrons emitted from an atomic
    layer Pb grown on a germanium substrate [Pb/Ge(111)] can be controlled using an
    electric field of light. The spin polarization of photoelectrons excited by a
    linearly polarized light is precisely investigated by spin- and angle-resolved
    photoemission spectroscopy. The spin polarization of the photoelectrons observed
    in the mirror plane reverses between p- and s-polarized lights. Considering the
    dipole transition selection rule, the surface state of Pb/Ge(111) is represented
    by a linear combination of symmetric and asymmetric orbital components coupled
    with spins in mutually opposite directions. The spin direction of the photoelectrons
    is different from that of the initial state when the electric field vector of
    linearly polarized light deviates from p- or s-polarization conditions. The quantum
    interference in the photoexcitation process can determine the direction of the
    spin vector of photoelectrons.
