摘要	Using angle-resolved photoemission spectroscopy, we study electronic structures of a Kagome metal YCr6Ge6. Band dispersions alongk(z)direction are significant, suggesting a remarkable interlayer coupling between neighboring Kagome planes. Comparing ARPES data with first-principles calculations, we find a moderate electron correlation in this material, since band calculations must be compressed in the energy scale to reach an excellent agreement between experimental data and theoretical calculations. Moreover, as indicated by band calculations, there is a flat band in the vicinity of the Fermi level at the Gamma-M-Kplane in the momentum space, which could be responsible for the unusual transport behavior in YCr6Ge6.
