报告摘要: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.

His research focus on following topics: 1) Synthesis of high-quality and large-size novel 2D monolayers, especially, a full spectrum of transition metal dichalcogenides (TMDs), the biggest family ever known in 2D materials. 2) Engineering of 2D materials such as lateral/vertical 2D heterostructure and alloy; 3) Physical properties of 2D monolayers such as 2D superconductivity (MoTe2 and NbSe2), 2D ferroelectricity (CuInP2S4), 2D ferromagnetism and 2D Wyle semi-metals (WxMo1-xTe2 and TaIrTe4). 3) Applications of 2D materials such as novel electronics (Semi-floating gate FET, Inorganic/organic PN junction and rectifier, Ferroelectrically non-volatile memory); Detector and sensors (Atom-thin photodetector, photoconductive switch and Microelectromechanical sensor); Coating and composite (high-temperature oxidation-resistant coating, binder-free fire-resistant wood coatings), energy and catalysis (Li-ion battery, supercapacitor, ORR, HER, etc).In this report, Professor Liu Zheng will also share some ideas on the writing and typesetting of the article.
