Title: Traces of charge density waves in NbS 2

Abstract

Among transition metal dichalcogenides (TMD), NbS 2 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 NbSe 2, TaS 2, and TaSe 2 all have CDW in at least one polytype. Here we report traces of CDW in the 2H polytype of NbS 2, 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 TaS 2 and TaSe 2. In conclusion, to understand this similarity and the faintness of the peaks, we discuss possible sources of local 1T polytype environment in bulk 2H-NbS 2 crystals.

FIG. 1 FIG. 1: Cristallographic structures of the three known polytypes of NbS2: 1T reported only in thin film7 or monolayer form8, and 2H and 3R found in bulk crystals form9. In the 1T polytype, the transition metal atom is in octahedral coordination and layers are stacked without rotation or in-plane translation.more » The 2H and 3R polytypes are composed of 1H single layers with the metal atom in trigonal prismatic coordination, but they differ by their stacking: rotation and no in-plane translation for 2H, in-plane translation and no rotation for 3R. The unit cell is indicated by solid red lines.« less
