The controllable synthesis of high quality low-dimensional materials, such as carbon nanotubes and graphene, is highly desired for both fundamental research and their industrial applications. It was also a great challenge in the society of low-dimensional materials. In the past we have paid great effort to explore the mechanism of low-dimensional materials’ growth and the potential routes towards the synthesis of the desired materials in a controllable manner. In this talk, I will present our theoretical study on the growth mechanism of low dimensional nanomaterials, the understanding of various experimental puzzles based on our theoretical results and the realization of the controllable synthesis experimentally.  My talk will cover the following contents:
 
(i) The theory of nucleation and growth of carbon nanotubes [1] and the strategies towards the chirality control during growth [2];
(ii) 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];
(iii) The kinetics of 2D materials growth and etching and the experimental control of their morphology.
 
These studies clearly showed that, beyond the calculation of various materials properties, theoretical exploration also can play a vital role in experimental design and material synthesis.

         Brief Bio
http://myweb.polyu.edu.hk/~tcfding/photo/dingfeng.jpg      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 and Chalmers University in Sweden from 2003 to 2005. From 2005, he joined Rice University as a Research Scientist until the end of 2008. From 2009-2016, 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 than 160 SCI papers in leading journals of natural science, with ~ 30 in Nature serious journals, PNAS, Sci Adv., PRL, JACS, ACIE. These publications were cited by > 5200 times (SCI) and his personal h-index is 40.
