In order to enhance the functionality of very high-frequency devices for Beyond 5G, there is a need to develop a physics-based method for analyzing the device operation mechanism. We have analyzed the information conversion between microscopic potential distribution and macroscopic current amplification in InGaAs-HEMTs using an extended free energy framework.
