Abstract Bismuth (Bi) is a topological crystalline insulator (TCI), which has gapless surface states (TSSs) protected by specific symmetry that strongly depends on the facet. Bi also promising electrochemical CO 2 reduction reaction (ECO RR) electrocatalyst for formate production. In this study, single‐crystalline rhombic dodecahedrons (RDs) exposed with (104) and (110) facets are developed. The RDs demonstrate very low overpotential high selectivity production (Faradic efficiency >92.2%)...
Abstract Rare-earth engineering is an effective way to introduce and tune magnetism in topological kagome materials, which have been acting as a fertile platform investigate the quantum interactions between geometry, topology, spin, correlation. Here, we report synthesis, structure, physical properties of titanium-based metals RETi 3 Bi 4 (RE = Yb, Pr, Nd) with various magnetic states. They all crystallize orthogonal space group Fmmm (No. 69), featuring distorted titanium lattices rare-earth...
The Mott insulator provides an excellent foundation for exploring a wide range of strongly correlated physical phenomena, such as high-temperature superconductivity, quantum spin liquid, and colossal magnetoresistance. A with the simplest degree freedom is ideal highly desirable system studying fundamental physics Mottness. In this study, we have unambiguously identified anticipated in van der Waals layered compound Nb3Cl8. phase, where interlayer coupling negligible, density functional...
Kagome metals AV3Sb5 (A = K, Rb, and Cs) with a V-Kagome lattice acting as fertile platform to investigate geometric frustration, electron correlation, superconductivity, nontrivial band topology, have attracted tremendous attention. Here we reported the structure properties of ATi3Bi5 family Ti-Kagome lattice, specifically focusing on electronic topology RbTi3Bi5. is found be non-superconducting metal strong quasi-two-dimensional feature, moderate small Pauli paramagnetism. Based first...

The quadratic band crossing points (QBCPs) at Fermi level in two-dimension have been proposed to be unstable under electron-electron interaction. possible interaction driven states include quantum anomalous Hall (QAH) state and various nematic ordered states. In this work, motivated by the discovery of ferromagnetic van der Waals layered metal-organic framework CrCl$_2$(pyrazine)$_2$, we theoretically propose that single layer CrCl$_2$(pyrazine)$_2$ might realize one or some these based on...
