Properties of c-doped gan
WebOct 29, 2024 · High-resistivity carbon doped GaN (C-GaN) is highly desirable for high electron mobility transistors (HEMTs) application to reduce the leakage current at high … WebFe and C doping in the GaN buffer are typically employed to enhance the confinement of the two-dimensional electron gas (2DEG) in the channel and thus reduce buffer leakage [1]. The doping process also introduces traps in the buffer, which are found to be responsible for current collapse (CC) in GaN HEMTs.
