The degradation of AlGaN/AlN/GaN high electron mobility transistors due to 1.8-MeV proton irradiation was measured at fluences up,to 3 x 10(15) cm(-1). The devices have much, higher mobility than AlGaN/GaN devices, but they possess similarly high radiation tolerance, exhibiting little degradation at flue ences up to 1 x 10(14) cm(-2). Decreased sheet carrier mobility due to increased carrier scattering and decreased sheet carrier density due to carrier removal are the primary damage mechanisms. The device degradation is observed as a decrease in the maximum transconductance, an increase in-the threshold voltage, and a decrease in the drain saturation current.
