Substrate‐Controlled Response Coefficients in Thin Films

open access: yesAdvanced Science, EarlyView.
Many material‐specific coefficients, which relate external stimuli and functional responses, are constants governed by atomic vibrations. This work demonstrates the concept of controlling such response coefficients by deformations, or strain, through strain‐induced changes in atomic vibrations.

Achieving Temperature‐Insensitive High Piezoelectricity by Reentrant Relaxor Transition

open access: yesAdvanced Science, EarlyView.
Although precision sensors and actuators demand piezoelectric materials with temperature‐insensitive high piezoelectricity, achieving such a property is challenging. This paper reports that reentrant relaxor transitions can break the trade‐off between high piezoelectricity and temperature insensitivity. High piezoelectricity (350 pC N−1) is achieved in

Probing ferroelectricity in highly conducting materials through their elastic response: persistence of ferroelectricity in metallic BaTiO3-d

open access: yes, 2019
The question whether ferroelectricity (FE) may coexist with a metallic or highly conducting state, or rather it must be suppressed by the screening from the free charges, is the focus of a rapidly increasing number of theoretical studies and is finally ...

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 ...

Chemically‐Disordered Transparent Conductive Perovskites With High Crystalline Fidelity

open access: yesAdvanced Science, EarlyView.
Kinetically arrested, chemically disordered perovskite thin films exhibit exquisite crystalline fidelity, broad IR–UV transparency, and low resistivity, despite incorporating five mismatched 3d–5d cations, including Cr and W. This study unites electronic correlation, cation diversity, valence complexity, and disorder—enabling new transparent conductors
