Zr Concentration-Dependent Sub-Lattice Phase-Field Model of Hf1-xZrxO2: Analysis of Phase Composition and Polarization Switching
Tae Ryong Kim, Sumeet K. Gupta
We develop a sub-lattice phase-field model of Hf1-xZrxO2 incorporating zirconium (Zr) concentration (x)-dependence. Our framework expands the time-dependent Ginzburg-Landau (TDGL)…

Thickness Dependence of Coercive Field in Ferroelectric Doped-Hafnium Oxide
Revanth Koduru, Sumeet Kumar Gupta
Ferroelectric hafnium oxide () exhibits a thickness-dependent coercive field behavior that deviates from the trends observed in perovskites and the predictions of…
