[2401.14547] Discovery of a Topological Charge Density Wave
2024年1月25日 · Here, using scanning tunneling microscopy, we directly visualize the bulk and boundary phenomenology of CDW in a topological material, Ta2Se8I. Below the transition temperature (TCDW = 260 K), tunneling spectra on an atomically resolved lattice reveal a large insulating gap in the bulk and on the surface, exceeding 500 meV, surpassing ...

2015年2月17日 · Here we investigate, using photoemission, X-ray scattering and scanning tunnelling microscopy, the canonical CDW compound 2 H -NbSe 2 intercalated with Mn and Co, and show that the conventional...
Intertwined charge and pair density orders in a monolayer high-Tc …
2023年5月29日 · Symmetry-breaking electronic phase in unconventional high-temperature (high-Tc) superconductors is a fascinating issue in condensed-matter physics, among which the most attractive phases are charge density wave (CDW) phase with four unit-cell periodicity in cuprates and nematic phase breaking the C4 rotational symmetry in iron-based superconduct...
Strongly enhanced charge-density-wave order in monolayer …
2015年7月20日 · Here we use terahertz Raman spectroscopy (down to 8 cm −1 Raman shift) to determine the CDW transition temperature TCDW in few-layer NbSe 2 by measuring the temperature dependence of both the...
Unusual competition of superconductivity and charge-density ... - Nature
2021年6月10日 · The CDW is completely suppressed at a critical pressure P2 ≈ 2 GPa together with a maximum Tc of about 8 K. In contrast to a common dome-like behavior, the pressure-dependent Tc shows an ...
Visualizing the Charge Density Wave Transition in 2H-NbSe2 in …
2013年7月8日 · We report the direct observation in real space of the charge density wave (CDW) phase transition in pristine 2H-NbSe2 using atomic-resolution scanning tunneling microscopy (STM). We find that static CDW order is established in nanoscale regions in the vicinity of defects at temperatures that are several times the bulk transition temperature Tcdw.
