Manipulating Ferroelectricity Without Electrical Bias: A Perspective

Advanced Physics Research, Volume 5, Issue 4, April 2026.
Alternatives to electrical bias to control ferroelectric polarization are highly desired for the development of ferroelectric‐based applications. The polarizing role of chemically engineered surfaces, the impact of chemical substitution and mechanical pressure, and light‐induced effects on the final polarization state are highlighted in this short ...

Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications

Advanced Materials, Volume 38, Issue 16, 17 March 2026.
This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.
