2021年1月15日 · Here, we experimentally demonstrate localized plasmons in a correlated 2D charge-density-wave (CDW) material: 2H-TaSe 2. The plasmon resonance can cover a broad …

2015年11月16日 · Few-layer tantalum diselenides (TaSe 2) are typical metallic TMDs exhibiting rich CDW phase transitions. However, a description of the structural, electronic and vibrational...

2017年2月24日 · We report on the emergence of robust superconducting order in single crystal alloys of TaSe 2− x S x (0 ≤ × ≤ 2). The critical temperature of the alloy is surprisingly higher …

2022年12月3日 · Recent research has proposed that the intrinsic quantum electronic state in the TaSe2 lattice could be improved by aligning the Van Hove singularity (VHs) with the Fermi …

2021年5月3日 · Here, we probe the CDW phase transition by the mechanical resonances of suspended 2H-TaS2 and 2H-TaSe2 membranes and study the effect of disorder on the CDW …

Charge density waves (CDW) in 2H-TaSe2 were studied by use of an ultra-low temperature STM over a wide temperature range between 90 mK and 300 K. The superlattice structure due to …

2000年7月1日 · Superconductivity in 2H-TaSe 2, a quasi-two-dimensional conductor, has been studied by the self-inductance method on single crystals. The transition temperature T c in …

2010年8月1日 · The in-plane and out-of-plane resistivities of both 2 H -TaSe 2 and 2 H -NbSe 2 were determined down to 10 K. For both compounds, the resistivity anisotropy shows notably …

2022年3月30日 · In this work, density functional theory (DFT) is used to catalog influences of van der Waals interactions and reduced dimensionality on the CDW atomic structures as a …

2023年11月10日 · Our results rule out the formation of a central-peak without full phonon softening for the CDW transition in 2 H -TaSe 2 and provide evidence for a novel precursor …
