Kagome metals (Mn3Sn, MnSn) with a two-dimensional network of corner-sharing triangles structure exhibit great potential in applications of future electronics and spintronics because of the unique combination of novel topological phases and high temperature magnetic ordering. Here, the ultra-thin Mn3-xSn film samples were successfully grown on Si(111) substrate by molecular beam epitaxy. And the crystal structure of the thin film sample was verified by XRD, RHEED, LEED, STM results. Furthermore, the flat band feature right in the Fermi surface was observed in ARPES results of our Mn3-xSn ultra-thin film.
