Dr. Junhao LIN’s group has more than 10 personnel, including postdoctoral, doctoral and postgraduate students. Combing high resolution transmission electron microscopy/scanning transmission electron microscopy (TEM/STEM) and first-principles calculation as a powerful synergetic tool, the research team is devoted to the study of the relationship between atomic structure and material properties in new 2D materials by means of combining experiment with theory.

Laboratory members have proficient electron microscopic characterizations and sample preparation techniques. At present, a new glove box interconnection system with a total investment of more than 8 million RMB has been preliminarily built in the laboratory, which realizes a clean and water, oxygen insulated environment for the whole process from sample growth, transfer, characterization to device manufacturing. Relying on the Picometer Electron Microscope Center and the Cryo Electron Microscope Center at Southern University of Science and Technology, our lab can achieve structure characterizations in the atomic level. The laboratory also has long-term cooperation with many universities and scientific research institutes at home and abroad. Some experiments can be carried out in high-end electron microscopy platforms such as Peking University, Japan National Institute of Advanced Industrial Science and Technology (AIST), Singapore National University, Oak Ridge National Laboratory in the United States, and some other cooperative research groups, which provide opportunities to communicate and learn with top scientific researchers.

Our research interests include:

1. High resolution in-situ scanning electron microscopy;

2. Applications of high spatial resolution and high energy resolution electron energy loss spectroscopy (EELS) in materials;

3. The relationship between structure and properties of new sensitive 2D materials and the atomic characterization of defect structures;

4. Growth and characterization of novel sensitive 2D materials.
