MoTe2: A Type-II Weyl Topological Metal
Zhijun Wang, Dominik Gresch, Alexey A. Soluyanov +6
Based on the ab initio calculations, we show that MoTe2, in its low-temperature orthorhombic structure characterized by an X-ray diffraction study at 100 K, realizes 4 type-II Weyl…
Resonance-state-induced superconductivity at high Indium contents in In-doped SnTe
Neel Haldolaarachchige, Quinn Gibson, Weiwei Xie +3
We report a reinvestigation of superconducting SnInTe at both low and high In doping levels. Analysis of the superconductivity reveals a fundamental change as a funct…
ZrSbRu, a new superconductor in the WSi structure type
Weiwei Xie, Huixia Luo, Brendan F. Phelan +1
We report that at low Ru contents, up to x = 0.2, the ZrSbRu solid solution forms in the hexagonal MnSi structure type of the host (x = 0), but that at…
Superconductivity in HfSbRu: Are Ru and Sb a critical charge-transfer pair for superconductivity?
Weiwei Xie, Huixia Luo, Elizabeth M. Seibel +2
We address the hypothesis that in intermetallic compounds, contrary to a long-standing view that considers electron count and crystal structure type as the only significant chemica…
Superconductivity in 3R-Ta1-xMxSe2 (M = W, Mo)
Huixia Luo, Weiwei Xie, Elizabeth M. Seibel +1
The 3-layer (3R) polytype of TaSe2-xTex shows a superconducting transition temperature that is between 6 and 17 times higher than that of the two-layer (2H) polytype. The remarkabl…
Superconductivity versus structural phase transition in the closely related BiRhS and BiRhS
Udhara S. Kaluarachchi, Weiwei Xie, Qisheng Lin +4
Single crystals of BiRhS and BiRhS were synthesized by solution growth and the crystal structures, thermodynamic and transport propertie…
Potential ring of Dirac nodes in a new polymorph of CaP
Lilia S. Xie, Leslie M. Schoop, Elizabeth M. Seibel +3
We report the crystal structure of a new polymorph of CaP, and an analysis of its electronic structure. The crystal structure was determined through Rietveld refinements of…
Gold-Gold Bonding: The Key to Stabilizing the 19-Electron Ternary Phases LnAuSb (Ln = La-Nd and Sm) as New Dirac Semimetals
Elizabeth M. Seibel, Leslie M. Schoop, Weiwei Xie +5
We report a new family of ternary 111 hexagonal LnAuSb (Ln = La-Nd, Sm) compounds that, with a 19 valence electron count, has one extra electron compared to all other known LnAuZ c…
Superconducting NbRuB derived through the fragment formalism
Weiwei Xie, Huixia Luo, K. Baroudi +3
We employ the chemical fragment formalism to perform a targeted superconductor search in the Nb-Ru-B system, yielding the orthorhombic metal-rich boride NbRuB, which displays BCS-l…
Polytypism, polymorphism and superconductivity in TaSe2-xTex
Huixia Luo, Weiwei Xie, Jing Tao +6
Polymorphism in materials often leads to significantly different physical properties - the rutile and anatase polymorphs of TiO2 are a prime example. Polytypism is a special type o…
A large new family of filled skutterudites stabilized by electron count
Huixia Luo, Jason W. Krizan, Lukas Muechler +6
Based on the interplay of theory and experiment, a large new family of filled group 9 (Co, Rh and Ir) skutterudites is designed and synthesized. The new materials fill the empty ca…
A new material for probing spin-orbit coupling in Iridates
Brendan F. Phelan, Jason Krizan, Weiwei Xie +2
We report the structure and magnetic properties of a new iridate compound, SrxLa11-xIr4O24, where the d-electron count of Ir and therefore its number of unpaired electrons can be t…
