Main Group Element Size and Substitution Effects on the Structural Dimensionality of Zirconium Tellurides of the ZrSiS Type

Tunability of the topological nodal-line semimetal phase in ZrSiX -type materials ( X=S, Se, TeHosen1, Dimitri2, Belopolski3 et al. 2017Phys. Rev. B158301381View full textAdd to dashboardCite

“…Single crystal X-ray diffraction (XRD) experiments were performed on a Kuma-Diffraction KM4 four-circle diffractometer equipped with a CCD camera using Mo Kα radiation. Rietveld refinements of the XRD data yielded the tetragonal space group P4/nmm with the lattice parameters close to those reported in the literature 46 . Electrical resistivity measurements were carried out within the temperature range 2-300 K and in applied magnetic fields up to 9 T using a conventional four-point ac technique implemented in a Quantum Design PPMS platform.…”

“…Similar to the ZrSiS structure they also crystallize in a PbFCl-type crystal structure with space group P 4/nmm 46 . Zr layers are separated by two neighboring X atoms layers, and sandwiched between a Si square net [see Fig.…”

“…The single crystals of ZrSiSe and ZrSiTe were grown by the vapor transport method as described elsewhere 46,47 . Their chemical composition was checked by energydispersive X-ray analysis using a FEI scanning electron microscope equipped with an EDAX Genesis XM4 spectrometer.…”

Nearly massless Dirac fermions and strong Zeeman splitting in the nodal-line semimetal ZrSiS probed by de Haas–van Alphen quantum oscillations

“…1a) are not only bonded to neighboring S and Si layers within the slab, but also bonded to S atoms in the adjacent slabs (see Fig. 1a) [43,48]. The 3D FS is also likely the cause of the "butterfly-shaped" anisotropic angular-dependence of magnetoresistance [51][52]71] seen in ZrSiS.…”

“…Among these materials, ZrSiS, which possesses layered tetragonal structure (see Fig. 1a) [43,45,48], shows distinct properties.…”
