Strain Correlated Linearly Polarized Photoluminescence in WSe2/WS2 Moire Superlattices

Abstract Reliable optical control of valley degrees of freedom in moiré excitons requires that the emitted polarization faithfully reflects the underlying valley state. Here, we show that linearly polarized photoluminescence from WSe2/WS2 moiré excitons is largely insensitive t...

Grain-boundary-induced Fe2CrNi-like ordering in austenitic stainless steels revealed by DFT-based Ising optimization

Predicting segregation behavior in concentrated multicomponent systems remains challenging due to strong solute–solute interactions and vast configuration space. Here, we show that in austenitic Fe0.8 − xCr0.2Nix (x = 0.075–0.15) stainless steels, segregation at a low-energy Σ5(2...
