Zirconium‐Rich Strategy in Ultrathin Hf0.5Zr0.5O2 toward Back‐End‐of‐Line‐Compatible Ferroelectric Random Access Memory

open access: yesAdvanced Science, EarlyView.
Here, the zirconium‐rich layer (Zr‐RL) strategy is developed in terms of ferroelectric (FE) properties, microstructure, switching kinetics, and reliability. Compared to the FE capacitor with conventional HZO film, the sub‐6 nm HZO/Zr‐RL/HZO stack exhibits a significantly low annealing temperature, an ultra‐low Vop, and an excellent ferroelectricity ...

Mechanism‐Aware Digital Twin for High‐Temperature Creep Prediction in Mo–Re Alloys

open access: yesAdvanced Science, EarlyView.
A digital twin framework enables real‐time monitoring of creep in refractory alloys and reveals dislocation‐drag‐induced Re segregation to grain boundaries. Inspired by this, La2O3 dispersion is introduced to suppress dislocation motion — concurrently mitigating Re segregation and enhancing creep resistance.
