Description
Physics based device modeling is a critical component of advanced radio frequency (RF) circuit and sub-system design and analysis. The device modeling suite under development in the Electronic Devices Branch (AFRL/RYDD) is divided into three main categories: first-principles modeling of semiconductor crystals, semi-classical electron transport simulation and characterization of high-frequency transistors, and physics based compact modeling of high-frequency transistors. Ab-initio characterization of semiconductor crystals is paramount for generating highly accurate compact models for RF designers. To this end, this research will investigate the application of density functional theory to extract accurate physical models used to represent electron-phonon scattering processes in semiconductor crystals. The calculation of deformation potentials for the beta phase of Gallium Oxide (beta-Ga2O3) is the central focus of this research opportunity. Successful calculation of these semiconductor crystal properties will enable accurate macroscopic beta-Ga2O3 metal oxide semiconductor field effect transistor simulations for advanced RF power electronics engineering applications.
