  - Engineering and enhancing the breaking of inversion symmetry in solids—that is,
    allowing electrons to differentiate between ‘up’ and ‘down’—is a key goal in condensed-matter
    physics and materials science because it can be used to stabilize states that
    are of fundamental interest and also have potential practical applications. Examples
    include improved ferroelectrics for memory devices and materials that host Majorana
    zero modes for quantum computing1,2. Although inversion symmetry is naturally
    broken in several crystalline environments, such as at surfaces and interfaces,
    maximizing the influence of this effect on the electronic states of interest remains
    a challenge. Here we present a mechanism for realizing a much larger coupling
    of inversion-symmetry breaking to itinerant surface electrons than is typically
    achieved. The key element is a pronounced asymmetry of surface hopping energies—that
    is, a kinetic-energy-coupled inversion-symmetry breaking, the energy scale of
    which is a substantial fraction of the bandwidth. Using spin- and angle-resolved
    photoemission spectroscopy, we demonstrate that such a strong inversion-symmetry
    breaking, when combined with spin–orbit interactions, can mediate Rashba-like3,4
    spin splittings that are much larger than would typically be expected. The energy
    scale of the inversion-symmetry breaking that we achieve is so large that the
    spin splitting in the CoO2- and RhO2-derived surface states of delafossite oxides
    becomes controlled by the full atomic spin–orbit coupling of the 3d and 4d transition
    metals, resulting in some of the largest known Rashba-like3,4 spin splittings.
    The core structural building blocks that facilitate the bandwidth-scaled inversion-symmetry
    breaking are common to numerous materials. Our findings therefore provide opportunities
    for creating spin-textured states and suggest routes to interfacial control of
    inversion-symmetry breaking in designer heterostructures of oxides and other material
    classes.@eng
