## Description

- description: "We report a direct observation of the electronic structure of monolayer
    SnTe on graphene by angle-resolved photoemission spectroscopy. By combining low-energy
    electron diffraction, momentum microscopy, core-level spectroscopy, and first-principles
    calculations, we show that the observed monolayer-limit electronic structure is
    consistent with a puckered even-layer biatomic-layer building block rather than
    a nonpuckered square-flat structure. The observed band dispersion and its polarization
    dependence are reproduced by a puckered structure with a substrate-renormalized
    buckling amplitude. We further show that graphene actively interacts with ultrathin
    SnTe by selecting its in-plane orientational texture, renormalizing the buckling
    amplitude, and modifying the local interfacial electrostatic environment in the
    monolayer limit. In comparison, multilayer SnTe exhibits a more ringlike momentum-space
    distribution, interlayer-split valence bands, and a stronger \U0001D45D-type character,
    revealing the onset of thickness evolution from an interface-stabilized puckered
    ultrathin limit toward a more bulklike state."
