Zhiyuan Liu earned his Ph.D. in Electrical and Computer Engineering from King Abdullah University of Science and Technology (KAUST) in 2025. His doctoral research was conducted in the KAUST Advanced Semiconductor Laboratory under the supervision of Professor Xiaohang Li.

Liu’s work focuses on the design, fabrication and performance optimization of III-nitride optoelectronic devices, including micro-LEDs, deep ultraviolet LEDs and ultraviolet photodetectors. His research emphasizes device structural design, physical modeling, micro- and nanofabrication, and surface and interface engineering to improve efficiency, reliability and scalability.

During his time at KAUST, Liu developed an etching-free fabrication approach for ultra-small micro-LEDs based on selective thermal oxidation. This work was recognized with the International Solid State Lighting Alliance’s 2025 Global SSL Award of Innovations Top 100, highlighting its contribution to improving device efficiency, stability and manufacturability.

Liu has authored more than 30 SCI-indexed journal publications, including 10 first-author papers in leading journals such as Light: Science & Applications, Optics Letters and Journal of Materials Chemistry C.

He is currently a professor at the Suzhou Institute of Nano-Tech and Nano-Bionics (SINANO), Chinese Academy of Sciences, where he continues to advance research on micro-LED technologies and III-nitride optoelectronic devices.
