Pressure-induced Superconductivity in AgSbTe2
Sudaice Kazibwe, Bishnu Karki, Wencheng Lu +8
AgSbTe2 is a well-known thermoelectric material with a high Seebeck coefficient and intrinsically low thermal conductivity, but its behavior under pressure remains largely unexplor…
Inverse Isotope Effect in the Ternary Perovskite Hydride SrPdH/D: A Signature of Quantum Zero-Point Fluctuations
Wencheng Lu, Mihir Sahoo, Roman Lucrezi +9
Guided by first-principles calculations, we demonstrate superconductivity in the ternary perovskite hydride SrPdH, synthesized at low pressure. Structural characterization…
High-pressure stabilization of Mg2IrH7: Structural proximity to high-Tc superconductivity
Shubham Sinha, Wencheng Lu, Mads F. Hansen +14
MgIrH is a metastable complex metal hydride with a predicted superconducting transition temperature as high as 170 K at ambient pressure. Following the synthesis of isomorp…
Isostructural phase transition and equation of state of type-I and type-VIII metallic sodium borosilicide clathrates
M. Demoucron, S. Pandolfi, Y. Guarnelli +10
Electronic properties of silicon-based clathrates can be tuned by boron incorporation into the silicon cage network. Sodium borosilicides clathrate outstands with uncommon stoichio…
Prediction and Synthesis of MgPtH: A Metallic Complex Transition Metal Hydride Stabilized at Ambient Pressure
Wencheng Lu, Michael J. Hutcheon, Mads F. Hansen +13
The low-pressure stabilization of superconducting hydrides with high critical temperatures (s) remains a significant challenge, and experimentally verified superconducting hyd…
