Graphene flake has been intensively studied over a decade, but a general strategy to produce materials with controlled level of quality is yet to be developed. 

Our group has been focusing on fabrication and application of graphene flakes with a wide range of quality and sizes. Through utilization of graphite intercalation compounds (GICs) as a source material, and differentiating solvents for exfoliation, we produced high quality graphene flakes in micron scales, and graphene quantum dots with sizes within few nanometers. 

The control of defect ratios in the materials lead to realization of superior and extraordinary properties, which have been demonstrated through applications in transparent electrode, energy devices, LEDs, and functional composites.

Seokwoo Jeon is currently an Associate Professor of Materials Science and Engineering at Korean Advanced Institute of Science and Technology (KAIST). He received his B.S degree in Materials Science and Engineering from Seoul National University (2000) and M.S degree from the same institute (2003). He recieved Ph.D in Materials Science and Engineering from University of Illiois at Urbana-Champaign (UIUC) where he developed an innovative technique of Proximity field nanoPatterning (PnP)for fabrication of bulk-scale 3D nano-patterned surfaces. After finishing his PhD, he joined Columbia University as a Postdoctoral fellow, where he developed his research in low-dimensional nanomaterials. since joining in KAIST as an assistant professor(2008), he has filed 48 patents and published 55 peer-reviewed journal articles (journal IF sum: 431.12, average IF of indexed article: 8.13), along with getting 28 research grants from Korean government and companies (LG Display, KCC, Samsung Electronics). He has been honored with various awards and commendations, recently including commendation from the minister of Korean Minstry of Science, ICT and Future Planning (2013), Front cover and 2014 Hot Papers of JMC C, Best of Advanced Optical Materials and front cover (2014), Invitation to speak at the new Quantum Dot Gordon Research Conference in 2014, Early Career Scientist Award from Korean Minstry of Science, ICT and Future Planning (2015).
