X‐Ray Diffractive Imaging: Needle‐Like Ferroelastic Domains in Individual Ferroelectric Nanoparticles (Adv. Electron. Mater. 5/2020)

In article 1901300, Edwin Fohtung and co-workers demonstrate an X-ray Bragg coherent diffractive imaging technique to spatially resolve the evolution of nanoscopic ferroelastic needle-like domains in individual BaTiO3 nanocrystals under external pressure. This provides a new paradigm for domain-boundary engineering and potential for nanoscale functional devices aided by pressure-induce structural phase transitions and ferroelectric phase transformation.
