题目：Flatland: the landscape of 2D materials
The one-atom-think crystal like graphene have fantastic properties and attracted tremendous interests in these years, which open a window to the landscape of the two-dimensional (2D) materials. There are a large variety of 2D materials beyond graphene that are to be explored. Using chemical solid reaction and chemical vapour deposition, we have successfully synthesized a wide spectrum of 2D materials including both single crystal bulk and atomically thin films.
In this talk, I will briefly introduce development of 2D materials over the past ten years and our recent work in this area, including the advances in the synthesis of various 2D materials, engineering of 2D materials and fabrication of 2D alloy. I will also discuss the unique physical properties of such as 2D superconductivity (MoTe2 and NbSe2), 2D ferroelectricity (CuInP2S4), 2D ferromagnetism and 2D Wyle semi-metals. In the last, I will introduce the potential applications of 2D materials for novel electronics, composite, energy and catalysis.

Dr. Zheng Liu received his B.S. degrees (2005) at Nankai University (China), and completed his PhD at National Centre for Nanoscience and Technology (NCNST, China), working on the synthesis and energy harvest of carbon nanotubes. He then worked in Prof Pulickel M. Ajayan and Prof Jun Lou’s groups as a joint postdoc research fellow (2010~2012) and research scientist (2012~2013) at Rice University (USA).
He has published more than 140 peer-reviewed papers in top journals including 16 papers in Nature and science serial journals (Nature Materials, Nature Nanotechnology, Nature Communications and Science Advances); 22 in Nano Letters; 18 in Advanced Maters; 9 in ACS Nano, with total citations more than 12000 and h-index of 48. These works have also been reported by many renowned media such as Science daily, Phy.org, EEE spectrum, etc., and also highlighted by the top journals such as Nature Physics, Nature Nanotechnology, Chem Int Ed, etc. He was also a recipient of the World Technology Award in Energy category in 2012. This award has been presented as a way to honour those in doing “the innovative work of the greatest likely long-term significance.” He was awarded the prestigious Singapore NRF Fellowship. He was also the awardee of the elite Nanyang Assistant Professorship in 2013.
