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)…
Lightweight True In-Pixel Encryption with FeFET Enabled Pixel Design for Secure Imaging
Md Rahatul Islam Udoy, Diego Ferrer, Wantong Li +3
Ensuring end-to-end security in image sensors has become essential as visual data can be exposed through multiple stages of the imaging pipeline. Advanced protection requires encry…
Reverse Designing Ferroelectric Capacitors with Machine Learning-based Compact Modeling
Diego Ferrer, Jack Hutchins, Revanth Koduru +2
Machine learning-based compact models provide a rapid and efficient approach for estimating device behavior across multiple input parameter variations. In this study, we introduce…
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…
Experimental Investigation of Variations in Polycrystalline Hf0.5Zr0.5O2 (HZO)-based MFIM
Tae Ryong Kim, Revanth Koduru, Zehao Lin +2
Device-to-device variations in ferroelectric (FE) hafnium oxide (HfO2)-based devices pose a crucial challenge that limits the otherwise promising capabilities of this technology. A…
