Fig. 5: 1T-NbS2 inclusions in 2H-NbS2.
Schematic visualisation of the proposed interpretation of the observed out-of-plane charge transport anomaly. The 2H-NbS2 crystal (structure in the centre) contains inclusion layers of 1T-NbS2 (highlighted in red). 1T-NbS2 undergoes a \(\sqrt {13} \times \sqrt {13}\) charge-density-wave (CDW) reconstruction. The Nb atoms in the CDW state are arranged into David-star-shaped clusters, superlattice of which is depicted on the right (only Nb atoms are shown, the dashed line marks the unit cell after the reconstruction). Each cluster contains an unpaired localised spin at the centre (red arrows on the right). The orientations of spins in the illustration are arbitrary and are not meant to suggest any particular ordering. This array of localised magnetic moments causes the itinerant electrons in the 2H-NbS2 bulk to experience Kondo scattering during the out-of-plane current flow (blue arrows).
