Monolayer van der Waals Kagome Lattice Enables High-Temperature Flat-Band Physics
Audio narration · Coming soon
This study demonstrates the realization of ideal two-dimensional monolayer kagome lattices within the van der Waals material family A2T3X4. Using nanofocused angle-resolved photoemission spectroscopy, researchers directly characterized the electronic structure down to the monolayer limit, revealing an isolated kagome-derived flat band just below the Fermi level. This advancement marks a significant step toward exploring high-temperature flat-band physics in two-dimensional systems.
