Professor; Yang Yang received his B.S. in Physics from the National Cheng Kung University in Taiwan in 1981, and his M.S. and Ph.D. in Physics from University of Massachusetts-Lowell, 1988 and 1992 respectively.
He joined Prof. Bryan Kohler’s group of UC-Riverside as a post-doc researcher from December 1991 to September 1992. Later, he joined UNIAX Corporation (now renamed as Du Pont Display) as a device physicist in October 1992. Yang joined the department of Materials Science and Engineering an Assistant Professor in January 1997 and subsequently became Associate Professor from July 1998. His research focuses on conjugated polymers and organics, polymer LEDs, and other related polymer electronic, photonic, and bio-devices. He has published more than 80 refereed papers and given more than 50 Invited presentations on his research work and has received 11 US patents.
Using conjugated organic compounds or polymeric materials as the active materials for the next generation semiconductor devices. Research topics cover LEDs, solar cells, memory devices and transistors.
