FerroX : A GPU-accelerated, 3D Phase-Field Simulation Framework for Modeling Ferroelectric Devices

Fundamental understanding and design of ferroelectric/multiferroic materials and devices for logic-in-memory and transistor enhancement is essential to enable low switching energies and thereby revolutionary power reductions in computing. Efficient modeling and simulations can provide in-depth insights into the underlying physics, as well as pave the road to facilitate researchers with reliable design tools for new microelectronic devices. In this talk, we will present a performance-portable, 3D phase-field simulation framework, FerroX, for modeling and design of ferroelectric-based microelectronic devices. FerroX is open-source (https://github.com/AMReX-Microelectronics/FerroX) and demonstrates a significant (15x) speedup on GPU architectures compared to the CPU counterparts. We will demonstrate the application of the code with simulations of multi-domain negative capacitance effects in Metal-Ferroelectric-Insulator-Metal (MFIM) and Metal-Ferroelectric-Insulator-Semiconductor-Metal (MFISM) devices. Additionally, we will report the latest upgrades, including the addition of strain in total free energy of ferroelectrics and the development of a micromagnetic module for modeling multiferroics.
