Abstract

The AlGaN/GaN high electron mobility transistor (HEMT) is considered a promising device for high-power, high-frequency, and high-temperature applications, as well as high-sensitivity sensors. However, several issues related to mobility, interface properties, and series resistance need to be clarified for a better understanding of the physical operation of AlGaN/GaN HEMTs and for further optimization of their performance. In this work, the electrical properties of AlGaN/GaN HEMTs, including the effects of series resistance, and interface properties with mobility degradation factors were investigated in detail. In addition, the low-frequency noise behavior of AlGaN/GaN HEMTs was examined with a carrier number fluctuation model that considered series resistance effects.
