  1. 1. Radiation Effects on GaN-based HEMTs for RF and Power Electronic Applications

    University essay from KTH/Tillämpad fysik

    Author : Wilhelm Holmberg; [2023]
    Keywords : High Electron Mobility Transistor; HEMT; Gallium Nitride; GaN; Silicon Carbide; SiC; Proton Radiation; Galliumnitrid; GaN; Kiselkarbid; SiC; Kisel; Si; HEMT; Transistor; Protonstrålning;

    Abstract : GaN-HEMTs (Gallium Nitride-based High Electron Mobility Transistors) have, thanks to the large band gap of GaN, electrical properties that are suitable for applications of high electrical voltages, high currents, and fast switching. The large band gap also gives GaN-HEMTs a high resistance to radiation. READ MORE
