The Ohio State University recently hosted the 7th United States Gallium Oxide Workshop, or GOX 2024, a pivotal workshop that brought together leading Ga2O3 research experts from around the world to discuss the latest advances in materials, device, and circuit development within the rapidly evolving field.
As a premier event in this advancing field, GOX 2024 provided a platform for attendees and participants to report on recent breakthroughs, identify critical scientific gaps, and foster actionable coordination across government, industry, and academia. The goal was to enable the rapid transition of new technologies from research to real-world applications.
The Aug. 5-7, 2024 event at Ohio State’s Knowlton Hall was co-chaired by Hongping Zhao, a professor in Electrical & Computer Engineering and Materials Science & Engineering at Ohio State; and Dr. Andrew J. Green, device team lead at the Air Force Research Laboratory (AFRL) Sensors Directorate.
“The Ohio State University is dedicated to excelling in semiconductor research and educating the next generations of workforce in this vital field.” Zhao said. “We are honored to host GOX 2024 at Ohio State this year. I would like to extend my sincere gratitude to our distinguished speakers, sponsors, committee members, student volunteers, and all attendees. Over the course of this three-day event, we have witnessed tremendous progress in the development of Ga2O3 materials, structures, devices and circuits.”
The material Ga2O3, or gallium oxide, is an ultra-wide bandgap semiconductor playing an increasingly important role in advancing efficiency, size and cost effectiveness in the development of cutting-edge power electronics.
Attendees at GOX 2024 explored a wide range of topics, including bulk and epitaxial growth, theory, modeling and simulations, materials characterization, device and circuit advancements, thermal management, electro-thermal codesign, and heterostructures.
Plenary speakers included Kohei Sasaki, of Novel Crystal Technology, Inc., Japan; Uttam Singisetti, of the University at Buffalo; and Chris Van de Walle, of the University of California, Santa Barbara. Also joining them at GOX were multiple invited speakers including James Speck, Yoshinao Kumagai, John S. McCoy, Adam Neal, Siddharth Rajan, Jianqiao Ye, and IMR executive director Steven Ringel, who also served on the conference’s advisory committee.
GOX 2024 also featured multiple technical sessions and a student poster session.
Ohio State was previously home to the GOX 2019 event, with Electrical and Computer Engineering professor Siddharth Rajan serving as technical program co-chair.
