Spin Excitations and Flat Electronic Bands in a Cr-based Kagome Superconductor
Zehao Wang, Yucheng Guo, Hsiao Yu Huang +33
In the quest for topology- and correlation-driven quantum states, kagome lattice materials have garnered significant interest for their band structures, featuring flat bands (FBs)…
Undulation-induced moiré superlattices with 1D polarization domains and 1D flat bands in 2D bilayer semiconductors
Xingfu Li, Sunny Gupta, Boris I. Yakobson
Two-dimensional (2D) materials have a high Föppl-von Kármán number and can be easily bent, much like a paper, making undulations a novel way to design distinct electronic phases…
Electron correlations in the kagome flat band metal
Fang Xie, Yuan Fang, Ying Li +7
Kagome metals offer a unique platform for investigating robust electron-correlation effects because of their lattice geometry, flat bands and multi-orbital nature. In the cases wit…
Colossal anomalous Stark shift in defect emission of undulated 2D materials
Sunny Gupta, Boris I. Yakobson
We report a strikingly new physical phenomenon that mirror symmetry breaking in undulated two-dimensional (2D) materials induces a colossal Stark shift in defect emissions, occurri…
Atomic-resolution structural and spectroscopic evidence for the synthetic realization of two-dimensional copper boride
Hui Li, Qiyuan Ruan, Cataldo Lamarca +3
Since the first realization of borophene on Ag(111), two-dimensional (2D) boron nanomaterials have attracted significant interest due to their polymorphic diversity and potential f…
Undulated 2D materials as a platform for large Rashba spin-splitting and persistent spin-helix states
Sunny Gupta, Manoj N. Mattur, Boris I. Yakobson
Materials with large unidirectional Rashba spin-orbit coupling (SOC), resulting in persistent-spin helix states with small spin-precession length, are critical for advancing spintr…
