William Wong
Biography
Dr. William S. Wong is a Professor in the Department of Electrical and Computer Engineering at the University of Waterloo, where he also serves as Director of the Giga-to-Nanoelectronics Centre and is a researcher at the Waterloo Institute for Nanotechnology.
Dr. Wong leads the Advanced Flexible Electronics Technology (AFET) group, which is dedicated to advancing high-performance, low-cost flexible electronics. The group is focused on the heterogeneous integration of silicon-based and Group III-nitride materials and devices to enable the development of flexible, large-area electronics on plastic substrates. These innovations are particularly relevant for applications in displays, image sensors, and energy generation systems, all of which benefit from enhanced functionality and mechanical flexibility. By leveraging the capabilities of the Giga-to-Nanoelectronics (G2N) Centre, the AFET group is advancing the synthesis of nanowire materials, processing of thin-film devices, and the development of hybrid devices using novel ink-jet printing and thin-film layer transfer techniques. The overarching goal of the group's research is to improve system performance while reducing fabrication costs.
Dr. Wong is an inventor with over 80 U.S. patents and has published more than 110 papers, including 45 invited talks, in the fields of electronic materials growth, processing, and characterization. He is an active member of the IEEE, the Materials Research Society, and serves on the committee of the Electronic Materials Conference. He is also on the Editorial Board of IEEE Electron Device Letters.
