Nanomaterials and Device Laboratory

Wonbong Choi, Ph.D., joined FIU as an Associate Professor in the Mechanical and Materials Engineering Dept. in June 2003 after spending 5 years as a project manager and a senior research scientist at SAMSUNG (SAIT). He was a leading scientist in the “Carbon Nanotubes for Tera-level Device” project with more than $1.0 M/year support from SAMSUNG and the Government of Korea. He was also involved in the field emission display project at SAMSUNG (SAIT), leading the team investigating the cold-cathodes (1998-2000).

Dr. Choi obtained his Ph.D in Materials Science and Engineering from the North Carolina State University (NCSU) in 1997. As a Post Doctoral Researcher he worked with Prof. J.J. Cuomo in the North Carolina State University during 1997-1998. In period spanning from 1988 to 1993, he worked as a Research Scientist at Agency Defense & Development, delving in fine ceramic composites and allied materials.

One of the remarkable achievements in his research career was the invention of “Carbon Nanotube Field Emission Display”, which was reported in Science and was covered extensively by news media around the world. His work has led to a recent demonstration by SAMSUNG of over 40-inch field emission flat panel display. In addition, Dr. Choi is credited to developing the vertical CNT-Field Effect Transistor and CNT based non-volatile memory devices. He has been involved in various cooperative projects such as fuel cell and lab-on-a-chip to name a few. His innovations, reported as news in the TRN News (January 2002) and MIT’s Magazine (June 2003), were the first to show some practical ways of making carbon nanotube based devices.

Over the years he has been exploring new materials, novel fabrication techniques, and novel device concepts for future nano-electronics and nano-sensor systems. A motivated and multidisciplinary skilled research team at FIU, pioneered by Dr. Choi, is currently focused on developing unique nanoscale devices for real-field applications. He has successfully conducted numerous granted projects in the domain of nanotechnology funded by AFOSR, SRC, DOE and Samsung. Dr. Choi is the author/co-author of over 70 patents (granted or applied), 3 book chapters, over 65 journal papers and over 45 conference proceedings. He has been invited to share his technological findings and knowhow at many international conferences, MRS, TMS, IEEE, APS and so on. He has served as a chair/committee member for several international meetings including “US-Korea Micro and Nano integrated Systems” (2005 NSF grant).

Major Professional Accomplishments:

Dr. Choi is an expert of Carbon Nanotube and its application. He has served as the Project Manager (2000-2003) for “Carbon Nanotubes for Tera-level Device” project with more than $1.0 M/year support from SAMSUNG and the Government of Korea. He has also been involved in the field emission display project at SAMSUNG (SAIT), leading the team investigating the cold-cathodes (1998-2000). Choi has invented the CNT Field Emission Display, reported in Science and covered extensively by news media around the world. His work has led to a recent demonstration by SAMSUNG, of over 30-inch field emission flat panel display. He has also served as the leader of the “Carbon Nanotubes for Microwave Generators” project from 2000-2001, supported by the Government of Korea (Ministry of Telecommunication and Information). Choi is credited to developing the vertical CNT-FET devices and CNT based non-volatile memory devices.

Choi is an author/co-author of over 40 patents (granted or applied), 3 book chapters, over 60 journal papers and over 40 conference proceedings. He has been invited to speak at many international conferences, e.g., a keynote presentation on “Trends in Nanotechnology 2002,” at the American Physical Society Meeting (2001), and a lecture on “Carbon Nanotube” at the Knowledge Foundation Conference (2001). He has served as a committee member for several international meetings such as “Nanotube 2003,” “IEEE-Nano 2004” and US-Korea-Japan Molecular Electronics Conference.

Choi has received several prestigious awards for his innovative research, e.g., the Gold Award from SAMSUNG in 2000 (for carbon nanotube field emission display development), Gold Technology Award from the Agency for Defense and Development, Korea Government in 1993 (for special ceramic composites development), and Awards for Best Paper of the Year 2001 and Best Patent of the Year 2001 from SAMSUNG (SAIT).
