Novel high voltage RESURF Al GaN /GaN HEMT with charged buff

发布时间：2020-12-30 13:29

　　A novel reduced surface field （RESURF） Al GaN /GaN high electron mobility transistor（HEMT）with charged buffer layer is proposed. Its breakdown mechanism and on-state characteristics are investigated.The HEMT features buried Fluorine ions in the GaN buffer layer both under the Drift and the Gate region （FDG）. The section of FDG under the drift region （FD） not only reduces the electric field （E-field） peak at the gate edge but also enhances the E-field in the drift region by the assisted depletion...
