TDA (Thermal Design Automation) for Multiscale Thermal Managements of GaN HEMTs

A TDA (Thermal Design Automation) system is proposed for multi-scale thermal simulation and design of Gallium Nitride (GaN) High Electron Mobility Transistors (HEMTs). By integrating first-principle calculations, machine learning potential-driven lattice dynamics, phonon Monte Carlo, and finite element methods, etc., TDA enables precise device-level electro-thermal simulations and designs. This approach has the potential to significantly enhance the accuracy and efficiency of thermal management for GaN HEMTs and other electronic devices.
