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…
