Resolving the electronic structure of Kagome metal ScV₆Sn₆

The unique shared-corner triangular crystal structure of Kagome lattice yields a band structure with Dirac point, flat band, and van Hove singularities, leading to strong correlations and non-trivial topological states. ScV₆Sn₆ is a new synthesized Kagome metal with a charge density wave transition at 92 K. Here, we carried out the Density Functional Theory (DFT) modeling of the electronic structure and measured the quantum oscillations in electrical resistance and magnetic torque in ScV₆Sn₆. Comparing the angular mapping of the resolved orbits with the DFT calculations provides a comprehensive study of the electronic structure and Fermi surface.
