Title: Orbital selectivity causing anisotropy and particle-hole asymmetry in the charge density wave gap of $2 H - {TaS}_{2}$

Abstract

Here, we report an in-depth angle-resolved photoemission spectroscopy study on 2H–TaS₂, a canonical incommensurate charge density wave (CDW) system. This study demonstrates that just as in related incommensurate CDW systems, 2H–TaSe₂ and 2H–NbSe₂, the energy gap (Δ_CDW) of 2H–TaS₂ is localized along the K-centered Fermi surface barrels and is particle-hole asymmetric. The persistence of Δ_CDW even at temperatures higher than the CDW transition temperature T_CDW in 2H–TaS₂, reflects the similar pseudogap behavior observed previously in 2H–TaSe₂ and 2H–NbSe₂. However, in sharp contrast to 2H–NbSe₂, where ΔCDW is nonzero only in the vicinity of a few “hot spots” on the inner K-centered Fermi surface barrels, Δ_CDW in 2H–TaS₂ is nonzero along the entirety of both K-centered Fermi surface barrels. Based on a tight-binding model, we attribute this dichotomy in the momentum dependence and the Fermi surface specificity of Δ_CDW between otherwise similar CDW compounds to the different orbital orientations of their electronic states that participate in the CDW pairing. Our results suggest that the orbital selectivity plays a critical role in the description of incommensurate CDW materials.

Traces of charge density waves in ${NbS}_{2}$

Journal Article Leroux, Maxime ; Cario, Laurent ; Bosak, Alexei ; ... - Physical Review B

Among transition metal dichalcogenides (TMD), NbS₂ is often considered as the archetypal compound that does not have a charge density wave (CDW) in any of its polytypes. By comparison, close isoelectronic compounds such as NbSe₂, TaS₂, and TaSe₂ all have CDW in at least one polytype. Here we report traces of CDW in the 2H polytype of NbS₂, using diffuse x-ray scattering measurements at 77 K and room temperature. We observe 12 extremely weak satellite peaks located at ±13.9° from ^→a* and ^→b* around each Bragg peak in the (h,k,0) plane. These satellite peaks are commensurate with the lattice viamore »« less

First-principles study of the low-temperature charge density wave phase in the quasi-one-dimensional Weyl chiral compound $({TaSe}_{4})_{2} I$

Journal Article Zhang, Yang ; Lin, Ling-Fang ; Moreo, Adriana ; ... - Physical Review B

Using ab initio density functional theory, we study herein the lattice phase transition of quasi-one-dimensional (TaSe₄)₂I. In the undistorted state, the strongly anisotropic semimetal band structure presents two nonequivalent Weyl points. In previous efforts, two possible Ta-tetramerization patterns were proposed to be associated with the low-temperature structure. Our phonon calculations indicate that the orthorhombic F222 CDW-I phase is the most likely ground state for this quasi-one-dimensional system. In addition, the monoclinic C2 CDW-II phase may also be stable according to the phonon dispersion spectrum. Since these two phases have very similar energies in our density functional theory calculations, both thesemore »« less

Pressure-induced charge density wave phase in $A g_{2 - δ} Te$

Journal Article Zhao, Yongsheng ; Yang, Wenge ; Schnyders, Harold S. ; ... - Physical Review B

Considerable excitement was generated by the observation of large and linear positive magnetoresistance in nonmagnetic silver chalcogenides. Renewed interest in these materials was kindled by the discovery that Ag₂Te in particular is a topological insulator with gapless linear Dirac-type surface states. High-pressure x-ray-diffraction studies, combined with first-principles electronic structure calculations, have identified three phase transitions as the pressure is increased: an isostructural transition identified with an electronic topological transition followed by two structural phase transitions. These recent studies were carried out on nominally stoichiometric Ag₂Te. For the present work we have prepared single-phase self-doped Ag_2-δTe samples with a well-characterized silvermore »« less

Superconducting energy gap of $2 H - NbS e_{2}$ in phonon spectroscopy

Journal Article Weber, F. ; Rosenkranz, S. ; Heid, R. ; ... - Physical Review B

We present a high-energy-resolution inelastic x-ray scattering data investigation of the charge-density-wave (CDW) soft phonon mode upon entering the superconducting state in 2H–NbSe₂. Measurements were done close to the CDW ordering wave vector qCDW at q=q_CDW + (0,0,l), 0.15 ≤ l ≤ 0.5, for T = 10K (CDW order) and 3.8K (CDW order+superconductivity). We observe changes of the phonon line shape that are characteristic for systems with strong electron-phonon coupling in the presence of a superconducting energy gap 2Δ_c and from which we can demonstrate an l dependence of the superconducting gap. Reversely, our data imply that the CDW energymore »« less

Quasiparticle interference, quasiparticle interactions, and the origin of the charge density wave in $2 H – {NbSe}_{2}$

Journal Article Arguello, C. J. ; Rosenthal, E. P. ; Andrade, E. F. ; ... - Physical Review Letters

We show that a small number of intentionally introduced defects can be used as a spectroscopic tool to amplify quasiparticle interference in 2H-NbSe₂ that we measure by scanning tunneling spectroscopic imaging. We show, from the momentum and energy dependence of the quasiparticle interference, that Fermi surface nesting is inconsequential to charge density wave formation in 2H-NbSe₂. We demonstrate that, by combining quasiparticle interference data with additional knowledge of the quasiparticle band structure from angle resolved photoemission measurements, one can extract the wave vector and energy dependence of the important electronic scattering processes thereby obtaining direct information both about the fermiologymore »« less
