  • Professor Wang Jinlan Reported Latest Research Results on Advanced Materials

Recently, the research group led by Professor Wang Jinlan of School of Physics SEU made great progress in the growth of van der Waals epitaxy of two-dimensional materials. The team proposed a new strategy to protect black phosphorus from degradation that is to use self-assembled organic monolayers by van der Waals epitaxy based on multi-scale simulation. The research result “Passivation Black Phosphorus via Self-Assembled Organic Monolayers by van der Waals Epitaxy” was published in Advanced Materials, top material advanced journal, Impact Factor 18.96.  In recent years, black phosphorus, a new type of two-dimensional semiconductor material consisting of elemental phosphorus, has attracted worldwide interest because of its unique physical and chemical properties. However, its fast degradation in the air hinders its practical application severely. Based on first principle and molecular dynamic simulation, and the organic molecule perylene tetracarboxylic dianhydride as the representative of the study, the team proposed to a use self-assembled organic monolayer by van der Waals epitaxy to protect black phosphorus from degradation. Advantages of this method are that it does not break the original properties of black phosphorus and that it affords new idea of protecting other two-dimensional materials lack of air stability. First author of the study is Zhao Yinghe, doctoral students of School of Physics SEU. Professor Wang Jinlan is the corresponding author. The research is funded by The National Science Fund for Distinguished Young Scholars, Jiangsu Science Fund for Distinguished Young Scholars and Specialized Research Fund for the Doctoral Program of Higher Education of China.

  • Latest Research Result of the Team Led by Professor Sun Litao, SEU, was Published in Nature Communications

Recently, the research result of the team led by Professor Sun Litao of School of Electronic Science and Engineering, Electrically driven cation exchange for in situ fabrication of individual nanostructures was published in Nature Communications 8, 14889(2017), with Southeast University as the first complete unit. SEU, PhD student Zhang Qiubo and young teacher Yin Kuibo were co-first author. Professor Sun Litao and Professor Zheng Haimei of University of California Berkeley, were co-corresponding author.


Cation exchange is always used to synthesize nano-materials with more complex structure and compostion which are not easily obtained using direct synthesis techniques, and it has been recognized as a popular tool for the synthesis of heterogeneous nanostructures. However, the current cation exchange is difficult to control the synthesis of individual heterogeneous nanostructure. Therefore, it hinders the integrated processing and manufacturing of high precision nano devices in the future.


The research team first proposed an electrically driven CE process. By controlling the contact position of ion source, it is possible to selectively prepare and modify individual nanocrystals with complex structure (Fig.1) and precisely control CE process to synthesize heterogeneous nanocrystals in different degree (Fig.2). The team proved electrically driven CE process was an effective way to control the synthesis of heterogeneous nanomaterials. And it also provided a visual and direct basis for understanding the microscopic mechanism of heterogeneous structure during CE process, which made the process and preparation of materials and devices in nano-scale more clear, more accurate and more controllable.


This research is another important achievement in the series of work of Professor Sun’s team in the field of high precision nano-processing and characterization in recent years. The related results were published in Adv. Funct.Mater. (2016), DOI: 10. 1002/adfm. 201603897 (Impact Factor 15.23), Nano Energy 30,771 (2016) (Impact Factor 11.553), 2D Mater. 4, 011001 (2017) (Impact Factor 9.611) and other important academic journals. The research has been funded by the China Outstanding Youth Fund Project of the National Natural Science Foundation, and International Cooperation Key Projects and National Major Scientific Research Equipment Development Projects (11525415, 51420105003, 11327901, 61274114).
