Oxygen Vacancy-Induced Monoclinic Dead Layers in Ferroelectric $H{f}_{x}Z{r}_{1-x}{O}_2$ With Metal Electrodes

Tanmoy Kumar Paul, Atanu Kumar Saha, Sumeet Kumar Gupta

In this work, we analyze dead layer comprising non-polar monoclinic (m) phase in $H{f}_{x}Z{r}_{1-x}{O}_2$ (HZO)-based ferroelectric (FE) material using first principles analysis. We show…
