AlGaN (aluminum gallium nitride) is a III-V compound semiconductor alloy that combines aluminum nitride and gallium nitride in a 1:1:2 stoichiometric ratio. This material is a wide-bandgap semiconductor widely used in high-power and high-frequency optoelectronic and electronic devices, where its superior thermal stability, electrical conductivity, and UV/blue light emission capabilities exceed those of conventional silicon. AlGaN is the critical active layer in ultraviolet LEDs, power amplifiers for RF/microwave applications, and high-electron-mobility transistors (HEMTs) for demanding aerospace and defense systems.
