Exascale Microelectronics Simulation Suite MicroEleX Offers Four GPU-Accelerated Codes for Ferroelectrics, Quantum Transport, Electrodynamics and Micromagnetics

The MicroEleX software package, developed under the U.S. Department of Energy’s Exascale Computing Project, offers a collection of open-source, GPU-scalable simulation tools built on the AMReX adaptive mesh refinement framework for semiconductor and microelectronics applications.

The suite currently contains four distinct codes:

FerroX – a 3D phase-field simulator for ferroelectric-semiconductor devices that solves the time-dependent Ginzburg-Landau equation for ferroelectric polarization, Poisson’s equation for electrostatic potential, and semiconductor carrier charge equations. It targets negative capacitance effects in Metal-Ferroelectric-Insulator-Metal (MFIM) and Metal-Ferroelectric-Insulator-Semiconductor-Metal (MFISM) semiconductor device stacks. Weak-scaling tests on NERSC systems showed up to 15× node-to-node speedup when moving from multicore CPUs to GPUs.

ELEQTRONeX – an electrostatic-quantum transport framework for semiconductor nanomaterials, currently applied to multi-tube carbon nanotube field-effect transistors (CNTFETs). The code couples an embedded-boundary electrostatic solver with a nonequilibrium Green’s function (NEGF) quantum transport module using tight-binding Hamiltonians and parallel Broyden self-consistency. Preliminary runs demonstrated solution of the electrostatic potential on billions of...
