Research

Two-dimensional (2D) materials have been one of the most extensively studied classes of materials due to the wealth of unusual physical phenomena that occur when charge and heat transport is confined to a plane. The reliable synthesis of uniform single- and few-layer 2D materials is an essential first step for characterizing the layer-dependent changes in their properties, as well as providing pathways for their integration into a multitude of applications.

(1) Our group developed the liquid metal chemical vapor deposition (LMCVD) strategy to achieve the precise assembly of the atoms, leading to the accurate atomic fabrication of 2D materials and their heterostructures.

(2) We also devote ourselves to the exploration of new properties and unique behaviors in the 2D materials and liquid metal, such as the smart response to the environmental stimulus, energy conversion, self-healing and other quasi-biological effects.

(3) We look forward to opening the new territory in the 2D materials and liquid metal and offering new concept to understand these new life forms.

Emerging applications based on 2D materials and liquid metal are just at the best stage and will continuously bring new breakthroughs.

    The universal growth of ultrathin perovskite single crystals is realized by designing an oriented solvent microenvironment induced by the interfacial electric field originated from the charge separation between solid and liquid phases. Such a strategy can fabricate a wide range of high-quality ultrathin perovskites single crystals, from layered to non-layered, organic to inorganic, and toxic to low-toxic lead-free perovskite.

    We present an Au-assisted chemical vapor deposition approach to selectively form SW and S2W antisite defects, whereby one or two sulfur atoms substitute for a tungsten atom in WS2 monolayers. Guided by first-principles calculations, they describe a new method that can maintain tungsten-poor growth conditions relative to sulfur via the low solubility of W atoms in a gold/W alloy, thereby significantly reducing the formation energy of the antisite defects during the growth of WS2.

    Yiran Ding#, Mengqi Zeng#, Qijing Zheng, Jiaqian Zhang, Ding Xu, Weiyin Chen, Chenyang Wang, Shulin Chen, Yingying Xie, Yu Ding, Shuting Zheng, Jin Zhao, Peng Gao, Lei Fu*
    First Pubulished: 7 October 2021

    We report the preparation of 2D materials with tunable interlayer spacing by introducing active sites (Ce ions) in 2D materials to capture and immobilize Pt single atoms. The strong chemical interaction between active sites and Pt atoms contributes to the intercalation behavior of Pt atoms in the interlayer of 2D materials and further promotes the formation of chemical bonding between Pt atom and host materials. Taking cerium-embedded molybdenum disulfide as an example, intercalation of Pt atoms enables interlayer distance tuning via an electrochemical protocol, leading to interlayer spacing reversible and linear compression and expansion.

Based on a designed molecular scaffold, the ultrathin Mo2GaC single crystals can be obtained during a chemical vapor deposition process.
