摘要：

Surface passivation effects were studied on AlGaN/GaN high-electron-mobility transistors (HEMTs) using SiO2 formed by plasma enhanced chemical vapor deposition. We discuss the role and the influence of passivation on the device performance and characteristics. An increase of I-Dmax and g(mmax) has been observed on the passivated (SiO2) HEMTs when compared with the unpassivated HEMTs. An improvement of F-T, F-max and device output power P-out was also observed after surface passivation. A good correlation is observed between pulsed and power measurements.
