Personal Home Page

Wide-gap semiconductor materials (e.g., GaN, Ga2O3, SiC) and devices can break the theoretical limits of traditional silicon-based devices, which are an important development direction for the next-generation power electronic devices. Prof. Hua has been researching GaN-based power devices, especially on advanced manufacturing technology, novel structure design, device physics, and reliability/stability investigation. Dr. Hua has published 70+ high-quality journal and conference papers with 1000+ citations, including IEEE EDL, IEEE TED, IEEE IEDM, IEEE ISPSD, et. She won the Charitat Award in 2017. Prof. Hua has joined SUSTech since Sep. 2018 and focuses on next generation wide-bandgap semiconductor device research.
