Prof Wang Nang Wang

BSc, MA, PhD


Professor Wang obtained his BA from CCIST Taiwan and PhD from Cambridge University. He was Scientific Advisor for EOS and MRL of ITRI Taiwan and a professor at NCTU Taiwan.

He was the founder, chairman and CEO of Quantum Optech Ltd, the co-founder and director of Arima Optoelectronics Co, and the founder of NanoGaN.

He was Chair Professor in Department of Physics at the University of Bath from 199 to 2007, and joined the Department of Electronic and Electrical Engineering in 2007. 


A central focus of Prof Wang's research is the high power and high efficiency LEDs for solid state lighting, backlighting, and medical applications. Bath’s team started the current GaN work in 1999. The early work of GaN by Dr W C Clark in Bath dated back to 1976 (Cathodoluminescence from GaN implemented with Arsenic or Phosphorus).

Prof Wang's team demonstrated the UK’s first electrically pumped 405 nm blue-violet laser diodes in June 2003. The team's innovative approach of using nano-structured compliant layers enabled them to grow very high quality and low strain GaN on Si and Sapphire. The team has also developed nano-imprint and fabrication technology for creating purposely designed nano-patterns.

Prof Wang's team has generated a significant IPR portfolio relating to GaN based light emitting diodes and laser diodes (33 patents filed, 26 granted in UK, USA, Japan, Taiwan, and China). In contrast to most academics, their close links with industries made them acutely aware of the advantage of close collaboration and outsourcing with industrial partners, which in turn reduces the requirement for various expensive pieces of capital equipment and minimises the time scale for commercialisation.
