Fig. 1: The crystal structure, BZs, XRD spectra and transport properties of TT’X.
From: Topological electronic states in HfRuP family superconductors
a The top view of the crystal, with brown, gray and green balls representing T, T’ and X atoms, respectively. b The perspective view of the crystal. c The bulk BZ, (001)-surface BZ and (100)-surface BZ. Hereafter, (001) [(100) or (010)] refers to the surface normal vector in terms of the Cartesian coordinates. d and e Indexed powder XRD spectra of ZrRuAs and HfRuP, respectively. Red stars are small amount of impurities. The left insets of (d) and (e) are photographs of ZrRuAs and HfRuP single crystals, respectively. The right insets of them are temperature dependent longitudinal resistivity of ZrRuAs and HfRuP at various magnetic fields. The magnetic fields are perpendicular to c axis and electronic current direction.
