Strain Fluctuations Unlock Ferroelectricity in Wurtzites

Advanced Electronic Materials, EarlyView.
In this study, Steven M. Baksa and his colleagues unveiled the atomistic mechanisms of ferroelectric reversal in Mg‐substituted ZnO where Mg cations induce strain fluctuations, triggering ferroelectricity via sequential reversal. They also demonstrate that Zn:Mg composition gradients along the polar axis promotes polarization reversal, providing new ...

How Shallow and Deep Defects Drive Carrier Dynamics in Tin‐Iodide Perovskites

Advanced Energy Materials, EarlyView.
This study investigates complex carrier dynamics in tin‐based perovskite films using transient absorption spectroscopy (TAS) across a broad spectral and temporal range. It identifies two deep electron trap states – surface Sn(IV) defects and tin interstitials – while also revealing shallow traps that repopulate band edges within picoseconds.

Heterogeneity of the Dominant Causes of Performance Loss in End‐of‐Life Cathodes and Their Consequences for Direct Recycling

Advanced Energy Materials, EarlyView.
Direct recyling of Li‐ion battery materials promises a low‐cost path towards a secure domestic supply of critical materials for batteries. Using cathode material from an end‐of‐life commercial Li‐ion cell, this work identifies the primary degradation mechanisms that diminish the performance of directly reused cathode materials and includes a discussion
