Chinese Abstract

简要回顾了AlGaN/GaN HEMT器件电流崩塌效应研究的进展,着重阐述了虚栅模型、应力模型等几种解释电流崩塌效应形成机理的模型和器件钝化、生长盖帽层等减小电流崩塌效应的措施。

English Abstract

A review on the progress and research of current collapse of AlGaN/GaN HEMTs is presented. The reason caused the current collapse is briefly introduced, including the model of virtual gate and bi as stress and so on. A few methods to decrease current collapse, such as passivating, growing capped layer are also described.
