Sep 2022: We report in Adv. Functional Materials a high-quality 400 °C-diamond with an average grain size of 650 nm and a thickness of 790 nm corresponding to an anisotropy ratio of 1.21.
Diamond is mostly grown at high temperatures (700–1000 °C), which limits its integration with many semiconductor technologies. Here, a high-quality 400 °C-diamond by modifying the gas chemistry at different nucleation stages, with a sharp sp3 Raman peak (FWHM≈6.5 cm−1) and high phase purity (97.1%), similar to 700 °C-diamond (>98%) is demonstrated. An average grain size of 650 nm with a thickness of 790 nm corresponding to an anisotropy ratio of 1.21 at 400 °C close to the best-reported of 1.12 at 700 °C is achieved. Congrats Mohamad and team!
Sep 2022: We report the first "Vertical Ga2O3 MOSFET With Magnesium Diffused Current Blocking Layer" in IEEE EDL.
We report two novel findings - first, a selective diffusion doping technique utilizing magnesium (Mg) doping spin-on-glass (SOG) as a dopant source to form a current blocking layer (CBL), and second, the first demonstration of a vertical Ga2O3 MOSFET with the Mg diffused CBL- Vertical Diffused Barrier Field-Effect Transistor (VDBFET). Congrats to Ke and the rest of the WBG Lab!
Apr 2022: Our paper on 2.8kV avalanche in GaN vertical PND is featured on the cover of the IEEE EDL April 2022 issue.
In this work, “2.8 kV Avalanche in Vertical GaN PN Diode Utilizing Field Plate on Hydrogen Passivated P-Layer”, a novel planar edge termination method is proposed and demonstrated. This method gives a vertical GaN PND the best performance with the lowest cost. Congrats Zhengliang and Ke!
Feb 2022: Congrats to Xinyi for being featured in IEEE TCVLSI Volume 8!
Says Prof. Srabanti Chowdhury who nominated Xinyi: “Xinyi joined the WBG-lab at Stanford and is currently in her 2nd year of her Ph.D. in electrical engineering. Her level of commitment to learning about the nitty-gritty of devices and contributing to solution-driven engineering is exemplary. She picked up a rather complicated, about 15-mask layer, device process and nailed it on her first try. Very gracious and always positive, Xinyi is a champ in our group. Very proud to be her Ph.D. advisor and can't wait to see her reach new heights!
Dec 2021: Congratulations Kelly for obtaining the Best Oral Presentation at the MRS 2021 Fall Meeting and Exhibit!
