On January 3, 2024, the Photonic Nose and Molecular Materials Group invited Lei Hairui, a researcher from Inner Mongolia University, to give a report titled “From Artificial Atoms to Artificial Molecules” in the lecture hall of the Institute of New Concept Sensors and Molecular Materials. The report was chaired by Prof. Liu Jing and attended by some faculty members and graduate students.

Lei Hairui first introduced the concept and frontier research background of artificial atoms, and expounded the key elements in the preparation process of artificial molecules from the dimensions of crystal surface structure, surface interface and optical properties of quantum dots. Then he introduced the work of his team using the surface reconstruction strategy to accurately control the crystal surface structure and luminous properties of quantum dots, and realize the directional splicing of artificial atoms to form artificial molecules.

After the report, Lei Hairui discussed relevant issues with the teachers and students present, and took a photo with the teachers.

Lei Hairui graduated from Shaanxi Normal University in 2017 with a Doctor of Science degree under the supervision of Prof. Liu Jing, and is currently a researcher and doctoral supervisor of Inner Mongolia University.
