Advanced Science, EarlyView.The GeTe acting as “molecule scissors” can tailor chemical bond, the breaking of Ag‐Se bonds and the formation of Ge‐Se bonds occur in the A‐SnSe matrix, along with the formation of Ag2Se precipitates. This process helps to optimize the thermoelectric properties, and also improves its mechanical properties to a certain extent.

A full-field crystal-plasticity analysis of bimodal polycrystals [PDF]
, 2020 International audienceA full field crystal plasticity modelling of bimodal polycrystals is presented. Bimodal polycrystals are generated using a controlled Laguerre–Voronoi algorithm, and a modified phenomenological law is used to take into account the ...

Advanced Energy Materials, EarlyView.Multiscale perspectives on how excess charges in soft lead halide perovskites induce operational instability in photovoltaic devices are presented. Localized carriers formed under thermodynamic non‐equilibrium states modify atomistic interactions and drive lattice distortions, accelerating device degradation.
