Semiconductor Research Lab (SRL) at Georgia Tech

A research group led by: Prof. Shyh-Chiang Shen

Major research Area: III-Nitride lasers, LEDs, detectors and transistors.

The SRL is actively doing researching on III-nitride (III-N) devices since 2005.  The major emphasis of these research projects are:

  • Wide bandgap semiconductor device design/simulation, fabrication, and characterizations
  • High-performance III-N integrated circuits and integrated photonics.

Current device research topics:

  1. GaN-based vertical electronic devices for kV-range power applications
  2. GaN-based bipolar transistor technology
  3. GaN-based UV avalanche photodetectors in linear-mode and Geiger-mode operations
  4. GaN-based Visible & UV lasers & LEDs

We have a 1,000 square-feet of class-1,000 cleanroom laboratory for semiconductor fabrication and measurement. We also access other fabrication facilities at Georgia Tech’s Institute of Electronic and Nanotechnology (IEN) to conduct our research projects.  Prof. Shen is also affiliated with Georgia Tech’s Center for Compound Semiconductors (CCS), the Package Research Center (PRC), and the Georgia Electronic Design Center (GEDC) under the IEN.

Prof. Shen’s research group has pushed the technology advancement toward a new state of the art.  His research group has achieved many “the first” in III-N device technologies over the years.  These device demonstration includes the first high-frequency operation of GaN heterojunction bipolar transistors (HBTs), the first GaN avalanche phototransistors, high-voltage AlGaN/GaN HEFTs, 1.2-kV class vertical PIN rectifiers, DUV lasers, and Geiger-mode GaN APDs.  The technology development interests are predominantly focused on creating viable and manufacturable semiconductor device technologies for commercial applications in 5 to 10 years.   Read on for an explanation of why we concentrate on gallium nitride (GaN).

About Prof. S.-C. Shen

We are constantly looking for highly motivated students with strong semiconductor physics background for III-N optoelectronic device and/or power electronic device research. The research involves experimental study of semiconductor device fabrication technology using cleanroom laboratories, computational simulations, and specialized characterization instruments.  Undergraduate students (GT only) who are interested in exploring these topics are encouraged to contact Prof. Shen directly.
