Abstract:
The controllable synthesis of high quality low-dimensional materials, such as carbon nanotubes and graphene, is highly desired for both fundamental researches and their industrial applications. In the past, we have paid great efforts to explore the mechanism of low-dimensional materials’ growth and the potential routes towards the controllable synthesis of the desired materials. In this talk, I will present our recent theoretical understanding on the growth of large area single crystalline graphene and structure-selective synthesis of carbon nanotubes, the theoretical explanation to various experimental puzzles and the experimental realization of their controllable synthesis. The contents will be covered in this talk include:
The theory of nucleation and growth of carbon nanotubes [1] and the strategies towards the chirality control during growth [2];
The theory on the mechanism of graphene CVD growth [3] and the strategies toward the quick synthesis of wafer sized graphene and its controllable growth [4];

Introduction:
Prof. Feng Ding obtained his Bs, Ms and PhD degrees from Huazhong University of Science and Technology, Fudan University and Nanjing University in 1993, 1996 and 2002, respectively. Then he was a Postdoctoral Research Fellow in Gothenburg University in Sweden from 2003 to 2005. From 2005, he joined Rice University as a Research Scientist until the end of 2008. From 2009 to 2016, he joined the Institute of Textile and Clothing of Hong Kong Polytechnic University as an Assistant Professor and Associate Professor (from 2013). From 2017, he joined UNIST as a Distinguished Professor and the IBS-CMCM as a group leader.
Prof. Ding’s research group’s research interests mainly focus on the computational method development, theoretical exploration of various carbon materials and 2D materials, especially on their formation mechanism, the kinetics of their nucleation, growth and etching. Prof. Ding has published more than180 SCI papers.
