摘要

报道了中子辐照引起的氮化镓功率器件寿命下降。在高强度中子束辐照下，以75 ~ 400 V的漏极电压对数百个器件进行了非稳态应力处理。通过观察具有统计学意义的中子诱导破坏性单事件效应(DSEEs)，可以准确地推断出地面场故障率。

A Study of Neutron Induced Single-Event Damage in AlGaN/GaN HEMTs

GaN power device lifetime degradation caused by neutron irradiation is reported. Hundreds of devices were stressed in off-state with various drain voltages from 75 V to 400 V while irradiated with a high intensity neutron beam. Observing a statistically significant number of neutron-induced destructive single-event-effects (DSEEs) enabled an accurate extrapolation of terrestrial field failure rates.
