Research summary
Gallium nitride (GaN) is poised to surpass silicon in high-speed, high-voltage applications—such as wireless communication and power electronics—enabling technologies from space communications to electric vehicles. Dr. Lan Wei, Canada Research Chair in Nanoscale Devices and Circuits, is advancing GaN-based devices and circuits to meet the requirements of commercial and industrial markets.
She and her research team are focusing on two areas: wireless communication in extreme environments, such as space missions and oil drilling applications, and high-energy-efficiency power delivery and power management systems for fast chargers, electric vehicles and data centres. Using a holistic approach that combines device physics, compact modelling, and innovative circuit design, their work will close key knowledge gaps and create tools for faster technology transfer. Ultimately, Wei is accelerating the commercialization of GaN technology and strengthening Canada’s leadership in this transformative sector.
