Multiaxial Aromatic‐Based Photoferroelectric Induced by Synergistic Intermolecular Interactions for Multidirectional Self‐Powered X‐Ray Detection

), and exceptional detection stability. Strikingly, the polycrystalline ferroelectric film also exhibits excellent self-powered X-ray detection behavior due to its biaxial ferroelectricity, indicating the potential for next-generation flexible and thin-film integrated devices.
