Mechanistic Insight into the Precursor Chemistry of ZrO2 and HfO2 Nanocrystals; towards Size-Tunable Syntheses

|
By Susan Cooper, Rohan Pokratath, Jette Katja Mathiesen, Valérie Waser
| ACS Publications
Introduction Group 4 metal oxides (titania, zirconia, and hafnia) exhibit interesting material properties such as high dielectric constant, wide bandgap, chemical and thermal resistance, fracture toughness, and high refractive index. Because of their high dielectric constant, ZrO2 and HfO2 are considered as a potential replacement for SiO2 (gate insulator) in field-effect transistors. (1,2) Furthermore, the mixed metal oxide Hf1–xZrxO2 is a ferroelectric material of interest.
