Monolayer van der Waals kagome lattice for high-temperature flat-band physics
Hyungkun Bong, Choongjae Won, Seongyong Lee +26
Kagome lattice materials host a remarkably rich landscape of novel quantum phenomena, all arising from the intrinsic interplay of topology, correlation, and frustration. While prev…
Nature of charge density wave in kagome metal ScV6Sn6
Seongyong Lee, Choongjae Won, Jimin Kim +9
Kagome lattice materials offer a fertile ground to discover novel quantum phases of matter, ranging from unconventional superconductivity and quantum spin liquids to charge orders…
Charge order landscape and competition with superconductivity in kagome metals
Mingu Kang, Shiang Fang, Jonggyu Yoo +13
In kagome metals AV3Sb5 (A = K, Rb, Cs), three-dimensional charge order (3D-CO) is the primary instability that sets the stage for other collective orders to emerge, including unid…
Universal Mechanism of Band-Gap Engineering in Transition-Metal Dichalcogenides
Mingu Kang, Beomyoung Kim, Sae Hee Ryu +7
Two-dimensional (2D) van-der-Waals semiconductors have emerged as a class of materials with promising device characteristics owing to the intrinsic bandgap. For realistic applicati…
Two-Dimensional Dirac Fermions Protected by Space-Time Inversion Symmetry in Black Phosphorus
Jimin Kim, Seung Su Baik, Sung Won Jung +5
We report the realization of novel symmetry-protected Dirac fermions in a surface-doped two-dimensional (2D) semiconductor, black phosphorus. The widely tunable band gap of black p…
Observation of tunable bandgap and anisotropic Dirac semimetal state in black phosphorus
Jimin Kim, Seung Su Baik, Sae Hee Ryu +7
Black phosphorus consists of stacked layers of phosphorene, a two-dimensional semiconductor with promising device characteristics. We report the realization of a widely tunable ban…
