      abstract     = {Artificial fabrication of a monolayer Kagome material can
                      offer a promising opportunity to explore exceptional quantum
                      states and phenomena in low dimensionality. Here, we have
                      systematically studied a monatomic Ni Kagome lattice grown
                      on Pb(111) by scanning tunneling microscopy/spectroscopy
                      (STM/STS) and density functional theory (DFT). Sawtooth edge
                      structures with distinct heights due to subsurface Ni atoms
                      have been revealed, leading to asymmetric edge scattering of
                      surface electrons on Pb(111). In addition, a local maximum
                      at about −0.2 eV in tunneling spectra represents a
                      manifestation of characteristic phase-destructive flat
                      bands. Although charge transfer from underlying Pb(111)
                      substrate results in a vanishing magnetic moment of Ni
                      atoms, the proximity-induced superconducting gap is slightly
                      enhanced on the Ni Kagome lattice. In light of
                      single-atomic-layer Ni Kagome lattice on superconducting
                      Pb(111) substrate, it could serve as an ideal platform to
                      investigate the interplay between Kagome physics and
                      superconductivity down to the two-dimensional limit.},
