Ferroelectricity in $\mathrm{Hf}{\mathrm{O}}_2$ from a chemical perspective

Jun-Hui Yuan, Ge-Qi Mao, Kan-Hao Xue +7

Ferroelectricity observed in thin film $\mathrm{Hf}{\mathrm{O}}_2$, either doped with Si, Al, etc. or in the $\mathrm{H}{\mathrm{f}}_{0.5}\mathrm{Z}{\mathrm{r}}_{0.5}{\mathrm{O}}_2$ form, has gained great technical significance. Howe…
