Order-Disorder Phase Stabilization by Pressure-Induced Charge Transfer Enhances the Ferroelectric Photovoltaic Effect in Multiferroic BaFe₄O₇. [PDF]

Adv Sci (Weinh)
A pressure‐driven charge transfer in multiferroic BaFe4O7 induces Fe valence disproportionation and structural distortion, drastically narrowing the bandgap and enhancing ferroelectric polarization. This synergistic optimization boosts photocurrent 2.5‐fold and is retained upon decompression, offering a promising strategy to overcome the ferroelectric ...
