The New Superconductor tP-SrPd2Bi2: Structural Polymorphism and Superconductivity in Intermetallics
Weiwei Xie, Elizabeth M. Seibel, Robert J. Cava
We consider a system where structural polymorphism suggests the possible existence of superconductivity through the implied structural instability. SrPd2Bi2 has two poly-morphs whi…
Differences in chemical doping matter - Superconductivity in Ti1-xTaxSe2 but not in Ti1-xNbxSe2
Huixia Luo, Weiwei Xie, Jing Tao +10
We report that 1T-TiSe2, an archetypical layered transition metal dichalcogenide, becomes superconducting when Ta is substituted for Ti but not when Nb is substituted for Ti. This…
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…
