Biography Summary

William S. Wong is a Professor in the Department of Electrical and Computer Engineering, Director of the Giga-to-Nanoelectronics Centre and a researcher at the Waterloo Institute for Nanotechnology at the University of Waterloo.

The Advanced Flexible Electronics Technology (AFET) group, led by Professor Wong, focuses on innovative solutions to enable high-performance and low-cost flexible electronics. The group is investigating heterogeneous integration of silicon-based and Group III-nitride materials and devices for the development of flexible large-area electronics on plastic substrates. This technology is used to create novel mechanically flexible systems for applications in displays, image sensors, and energy generation systems having enhanced functionality. The group uses the capabilities of Giga-to-Nanoelectronics (G2N) Centre to synthesize nanowire materials, process thin-film devices and develop novel nanowire/thin-film hybrid devices through novel ink-jet printing and thin-film layer transfer processes. The goal of the research is to develop innovative processes and materials that will improve system performance and reduce fabrication costs.

Professor Wong is the holder more than 80 U.S. patents and has 110 publications, including 45 invited talks, in the area of electronic materials growth, processing and characterization. He is a member of the IEEE, the Materials Research Society, a committee member of the Electronic Materials Conference, and is on the Editorial Board of IEEE Electron Device Letters.
