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

Abstract

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 via 3^→q–^→q'=^→a*, where ^→q' is the 120° rotation of ^→q, and define two √13a × √13a superlattices in real space. These commensurate wave vectors and tilt angle are identical to those of the CDW observed in the 1T polytype of TaS₂ and TaSe₂. In conclusion, to understand this similarity and the faintness of the peaks, we discuss possible sources of local 1T polytype environment in bulk 2H-NbS₂ crystals.

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

Journal Article Zhao, J. ; Wijayaratne, K. ; Butler, A. ; ... - Physical Review B

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 innermore »« less

Atomic force microscopy of charge density waves and atoms on 1T-TaSe sub 2 , 1T-TaS sub 2 , 1T-TiSe sub 2 , and 2H-NbSe sub 2

Journal Article Garnaes, J ; Gould, S A.C. ; Hansma, P K ; ...

In this paper, atomic force microscopy (AFM) measurements on TaSe{sub 2} and 1T-TaS{sub 2} will be presented clearly resolving both the atoms with a z deflection of {approx} 0.5 {angstrom}. All of the measurements have been carried out at room temperature using freshly cleaved crystals in air. It has been possible to distinguish very clearly between the commensurate CDW structure on 1T-TaSe{sub 2} and the incommensurate CDW structure on 1T-TaS{sub 2}. For the commensurate CDW structure on 1T-TaSe{sub 2}, the rotation angle between the atomic lattice and the CDW superlattice is measured as 14.2{degree} {plus minus} 0.5.

Spectroscopic signature of moment-dependent electron–phonon coupling in 2H-TaS₂

Journal Article Wijayaratne, Kapila ; Zhao, Junjing ; Malliakas, Christos ; ... - Journal of Materials Chemistry C

Here, charge density wave (CDW) order is ubiquitous among low-dimensional electronic systems, as realized in layered materials such as various 1T and 2H polytypes of transition metal dichalcogenides (TMDs). In particular, 2H-TaS₂, a prominent member of the vast family of TMDs, hosts a canonical CDW phase transition whose mechanism remains controversial even after decades of research. Using state-of-the-art angle resolved photoemission spectroscopy (ARPES) measurements, we report, for the first time, pronounced many-body renormalizations in 2H-TaS₂. These renormalizations are manifested by the presence of multiple slope changes, known as “kinks”, in the electronic dispersions. The temperature independence of the kink energiesmore »« less

High-Q-resolution scattering using synchrotron x radiation: 2H-TaSe/sub 2/ and NbSe/sub 3/

Journal Article Fleming, R M ; Moncton, D E ; Axe, J D ; ... - Phys. Rev. B: Condens. Matter; (United States)

We report high-resolution synchrotron x-ray-scattering measurements on two compounds with charge-density-wave (CDW) phase transitions, 2H-TaSe/sub 2/ and NbSe/sub 3/. In these materials the scattering from the CDW superlattice is typically more than 3 orders of magnitude smaller than that of the host lattice. The increased flux available with a synchrotron source allows one to study weak CDW scattering with a Q resolution on the order of 10/sup -4/ A/sup -1/, which is 1 to 2 orders of magnitude better than that attainable with a rotating-anode source. In the case of 2H-TaSe/sub 2/, we were able to measure finite widths ofmore »« less

Spectroscopy of dichalcogenides and trichalcogenides using scanning tunneling microscopy

Journal Article Wang, Chen ; Slough, C G ; Coleman, R V

The scanning tunneling microscope has been used to measure the charge-density wave (CDW) energy gap in the layer structure compounds 1T-TaSe{sub 2}, 1T-TaS{sub 2}, 1T-VSe{sub 2}, 1T-TiS{sub 2}, 2H-TaSe{sub 2}, 2H-TaS{sub 2} and 2H-NbSe{sub 2}. The measured values show a systematic dependence on the strength of the CDW and calculated values of 2{Delta}/k{sub {Beta}}T{sub c} are compared. CDW gap measurements on the trichalcogenide compounds NbSe{sub 3} and TaS{sub 3} are also included.
