Advanced Science, EarlyView.Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses

Advanced Electronic Materials, EarlyView.The structural characteristics and resonant mechanical behavior of suspended microbridges comprised of single‐crystalline SrTiO3 that has been grown on silicon are presented. Due to differences in thermal expansion between the SrTiO3 and silicon, we find that the resonant frequencies of the microbridges are not only enhanced, but also hyper‐sensitive ...

Achieving Large Uniaxial and Homogeneous Strain in Two‐Dimensional Materials
Small, EarlyView.Strain is a powerful tool for tuning the electronic, magnetic, and topological properties of 2D materials ‐ particularly at high values (>3$>3$%) where many electronic and structural transitions are predicted. Our high‐yield preparation and device strain platform overcomes existing strain limitations (often <1.5$<1.5$%), enabling repeatable and ...
