Welcome to the So Group!

Prof. Franky So

Professor Franky So, Principal Investigator and Walter and Ida Freeman Distinguished Professor, received his Ph.D. from the University of Southern California. He worked for Motorola and OSRAM Opto-Semiconductors for 14 years before he became a professor at the University of Florida. He was a Rolf E. Hummel Professor of Electronic Materials in the Department of Materials Science and Engineering at the University of Florida. In 2015, he joined North Carolina State University.

Prof. So is currently a Fellow of the National Academy of Inventors, MRS, IEEE, SID, OSA, and SPIE. He is the Editor-in-Chief of Materials Science and Engineering Reports, and Associate Editor of four other research journals. He chairs the OLED Symposium of the SPIE Optics and Photonics conference. Prof. So holds over 100 issued patents. He has over 200 publications and maintains a Google H-index of >80.

Research Areas


We investigate carbon-based organic electronic and semiconducting devices that include:

  • Organic light-emitting diodes (OLEDs)
  • Organic photodetectors (OPDs)
  • Organic photovoltaics (OPVs)
  • Organic field-effect transistors (OFETs)

We study and develop devices that include:

  • Inorganic semiconductor materials quantum dots for infrared (IR) sensing
  • Hybrid organic lead halide perovskites for high-efficiency solar cells
  • Heterojunction metal oxides for ultraviolet (UV) photodetectors
  • High-gain permeable vertical transistors

Our research focuses on:

  • Revealing the physical properties of novel electronic/semiconducting materials with advanced characterization methods
  • Designing new device architectures
  • Developing new processing methods for high-performance optoelectronic devices
