Trapping characteristics and parametric shifts in lateral GaN HEMTs with SiO₂/AlGaN gate stacks

Recovery transients following blocking-state voltage stress are analyzed for two types of AlGaN/GaN HEMTs, one set of devices with thick AlGaN barrier layers and another with recessed-gate geometry and ALD SiO₂ gate dielectric. Results show temperature-invariant emission processes are present in bot...

description Recovery transients following blocking-state voltage stress are analyzed for two types of AlGaN/GaN HEMTs, one set of devices with thick AlGaN barrier layers and another with recessed-gate geometry and ALD SiO₂ gate dielectric. Results show temperature-invariant emission processes are present in both devices. Recessed-gate devices with SiO₂ dielectrics are observed to exhibit simultaneous trapping and emission processes during post-stress recovery.
