IEEE Toronto Electronic Devices Society is proud to invite you to a distinguished lecture by Dr. Yuhao Zhang of University of Hong Kong. Join us Tuesday, 25 August 2026 at 10AM (EST) This is a hybrid event, feel free to join us remotely if you cannot make it🙌 Refreshments will be provided Abstract ————————————————————— Power electronics technologies provide electrical energy conversion using semiconductor devices and passive components. The global power semiconductor market reaches US$50 billion and is rapidly expanding, driven by applications like AI data centers, electric vehicles, consumer electronics, electric grids and renewable energy processing. Power device advances are driven by materials and device architectures. In addition to using wide-bandgap (WBG) or ultrawide-bandgap (UWBG) materials, multidimensional architectures – such as superjunction, multi-channel and multi-gate – can also improve device performance. These structures enable electrostatics engineering in additional dimensions and bring the benefits of geometrical scaling into power devices. This talk presents our efforts in developing multidimensional power devices in WBG and UWBG semiconductors, with the scope covering device and material innovation, packaging and thermal management, as well as circuit applications. These devices have achieved performance beyond the respective material limits of 1-D devices and hold great potential for advancing the speed, efficiency, and form factor of power electronics systems; some of them have reached initial commercialization. These devices also provide an exciting platform to explore the fundamental material properties and carrier transports under the concurrence of high electric field and high current density in sub-micron-second switching transients.
