Two New Molecular Nitrogen Phases near Megabar Pressures
Alexander F. Goncharov, Elena Bykova, Iskander Batyrev +7
Molecular nitrogen exhibits remarkable structural diversity near the polymeric transition, where multiple phases are metastable. Here, we report two new molecular phases. The first…
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…
Building Wet Planets through High-Pressure Magma-Hydrogen Reactions
Harrison Horn, Allona Vazan, Stella Chariton +2
Close-in transiting sub-Neptunes are abundant in our galaxy \cite{fulton2017california}. Planetary interior models based on their observed radius-mass relationship suggest that sub…
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…
Hydrogen-rich hydrate at high pressures up to 104 GPa
Alexander F. Goncharov, Elena Bykova, Iskander Batyrev +10
Gas hydrates are considered fundamental building blocks of giant icy planets like Neptune and similar exoplanets. The existence of these materials in the interiors of giant icy pla…
Origin of Pressure-Induced Structural Instability in CsPbX Photovoltaic Perovskites
Sizhan Liu, Sandun Amarasinghe, Mo Li +6
Under external stimuli, lead halide perovskites exhibit large atomic fluctuations, impacting optical and electron transport properties that affect device performance in operational…
