Breaking of Thermopower–Conductivity Trade‐Off in LaTiO3 Film around Mott Insulator to Metal Transition

Thermoelectric power-factor enhancement by 2 orders of magnitude is discovered beyond the Mott insulator to metal transition in compressively strained LaTiO3 films. Both conductivity and thermopower increase in the n-type region, breaking the conventional trade-off between them. Tuning oxides close to their Mott transition through epitaxial strain is...

Universal‐Descriptors‐Guided Design of Single Atom Catalysts toward Oxidation of Li2S in Lithium–Sulfur Batteries

Three out of nine parameters identified in this work can serve as efficient descriptors by which two excellent single atom catalysts (SACs) of MoN4@G and WN4@G with the best redox performance are screened. This descriptors-guided design strategy can be extended to a wider range of SACs, e.g., interface and more complex coordination environments of metal...
