Prof. Yuh-Renn Wu graduated from the Department of Physics (1998) and the Graduate Institute of Communication Engineering(2000), National Taiwan University. After two years of military service, he obtained his Ph.D. degree in EECS at the University of Michigan, Ann Arbor, in 2006. He became an Assistant Professor at the Graduate Institute of Photonics and Optoelectronics, National Taiwan University, in 2007. His research work starts with nitride-based HEMTs for high-power and high-frequency applications. After, he started to work on device modeling on InGaN nitride-based LEDs and collaborated with industries to solve the inaccuracy issues in InGaN QW LEDs. He developed an accurate numerical simulation method for analyzing carrier transport in the InGaN alloy system considering random alloy disorder. His lab is the first group in the world to use a fully 3D model to simulate carrier transport and localization, where he found that random alloy fluctuation is crucial in carrier localization and the key issue affecting the device's forward voltage and efficiency. In 2014, He started collaborating with Prof. Marcel Filoche to apply his novel Localization landscape model to model the disorder system with consideration of random alloy fluctuation and quantum effects simultaneously. Their approaches significantly provided an efficient 3D simulation tool to consider quantum effects in the random alloy system, where the speed could be more than a thousand times faster in a large and complicated system. 

He brings his simulation tools into powerful TCAD software in modeling III-V materials called multi-dimensional DDCC (drift-diffusion charge control) solver. This tool is now widely used in LED-related companies and academics, where over thousands downloads from 55 different countries worldwide have been achieved. He and is licensed to many LED-related companies such as Epistar, Meta, Apple, and Playnitride, etc... His work was awarded the Ta-You Wu Memorial Award from the National Science and Technology Council in 2015. He and Prof. Marcel Filoche were awarded Franco-Taiwanese Scientific Grand Prize in 2023.
