Elucidating active sites and decomposition mechanisms for oxythiomolybdate clusters (Mo2O2Sx, x = 6;8) as catalyzers for hydrogen evolution reactions

Electrochemical Science Advances, 2022
We investigated the decomposition mechanism of Mo3S13 (chalcogenides) and Mo2O2Sx(x = 6,8) through Density Functional Theory, in particular Mo2O2Sx. Oxythiomolybdates are more stable than chalcogenides, and decompose through cathodic reactions, while ...

Atomic‐Scale Detection of Néel Vector Switching in the Single‐Layer A‐Type Antiferromagnet Cr2S3‐2D

Advanced Materials, EarlyView.
Interfacial electron donation from graphene redistributes charge within single‐layer Cr2S3‐2D, preferentially accumulating at the lower Cr/S plane. The resulting minute magnetic imbalance lifts the equivalence of the two magnetic sublayers, enabling atomic‐resolution identification and field‐induced control of Néel‐vector states in a two‐dimensional A ...

Moiré‐Induced Symmetry Breaking of Charge Order in van der Waals Heterostructures

Advanced Materials, EarlyView.
A uniaxial moiré potential in misfit (MS)1+δTaS2 heterostructures selectively reshape charge order: the embedded 1H‐TaS2 layer hosts an incommensurate charge‐density wave, fragmented into nanometer domains and stripped of threefold symmetry. Superconductivity, however, remains uniform and fully gapped, revealing heterosymmetry stacking as a selective ...

Heterogeneous distribution of sodium for high thermoelectric performance of p-type multiphase lead-chalcogenides

, 2015
Despite the effectiveness of sodium as a p-type dopant for lead chalcogenides, its solubility is shown to be very limited in these hosts. Here, a high thermoelectric efficiency of ≈2 over a wide temperature range is reported in multiphase quaternary ...

Extreme Bond Ionicity in Mg─Te Chalcogenides for Ultrathin Low Voltage Selector‐Only Memory beyond the Leakage Scaling Limit

Advanced Materials, EarlyView.
Mg─Te chalcogenides address the leakage scaling trade‐off in ultrathin selector‐only memory. Structural partitioning in multiphase Mg─Te, combined with highly ionic Mg─Te bonding and Hf interfacial engineering, supports reliable 5 nm thickness operation at low write voltage with suppressed leakage current, narrow threshold voltage distributions, 10 ns ...
