2014年12月2日 · The $s{d}^{2}$ graphene is characterized by bond-centered electronic hopping, which transforms the apparent atomic hexagonal lattice into the physics of a kagome lattice that may exhibit a wide range of topological quantum phases.

2018年7月23日 · Here, we propose a class of systems made of real atoms, namely carbon atoms with realistic physical interactions (dubbed here ``kagome graphene/graphyne''). Density functional theory calculations reveal that these kagome lattices offer a controllable way to realize robust flat bands sufficiently close to the Fermi level.

2025年1月11日 · Here we induce zero-energy states into a semiconducting Kagome graphene by inserting π-radicals at selected locations. We utilize the on-surface reaction of tribromotrioxoazatriangulene molecules to synthesize carbonyl-functionalized Kagome graphene on Au(111), thereafter modified in situ by exposure to atomic hydrogen

2022年8月11日 · A representative example is the predicted formation of localized pseudo-Landau levels (PLLs) with kagome lattice in tiny-angle twisted bilayer graphene (TBG) with $\ensuremath{\theta}<0.3\ifmmode^\circ\else\textdegree\fi{}$ when the graphene layers are subjected to different electrostatic potentials.

2020年2月15日 · Kagome graphene is a single-layer carbon nanosheet possessing Kagome bands. Here, we propose two types of three-dimensional (3D) Kagome graphene networks (KGNs), which are formed by linking one-dimensional (1D) Kagome graphene nanoribbons.

2024年12月16日 · Our 2D kagome structure, formed by creating patterned nano pores in the graphene sheet, nomenclatured as porous graphene-based kagome lattice (PGKL), is inspired by the recent bottom-up synthesis of similar structures.

kagome-like lattices and what would be the physics of strong correlation in them. In this paper, we identify, by first-principles total-energy calculations, a family of two-dimensional (2D) carbon kagome-like structures (to be termed “kagome graphene/graphyne”), which can host flat bands and relevant physical phenomena.

2023年7月20日 · Here we analyze the electron–electron correlation effects via Hubbard mean-field approximation on the topological phases of 2D and quasi-1D graphene-Kagome lattices. The 2D spin conductivity phase's diagrams describe metallic, trivial, and topological insulating behaviors, considering different energy coupling and electronic occupations.

2025年1月17日 · where a is the lattice constant and \({\omega }_{D}\) is the Dirac degeneracy frequency in Kagome lattices corresponding to t = t 2 - t 1 = 0 (\(t=\frac{2b-c}{c}\)).As t = 0, the distance between ...

2022年12月21日 · We highlight the connection between theoretical ideas and experimental observations, and the bond between quantum interactions within kagome magnets and kagome superconductors, as well as their...
