Orthorhombic‐like atomic arrangement in hafnium‐oxide‐based nanoparticles

Size effect on ferroelectricity in nanoparticles (NPs) has been an important issue for decades. For NPs with a perovskite‐type crystal structure, which are the most popular ferroelectrics, ferroelectricity is believed to disappear for sizes below a critical value. However, newly discovered hafnium‐o...
