Two-dimensional (2D) materials consist of conductors, semiconductors, ferromagnets, superconductors, ferroelectrics, etc.. It is difficult to realize specific functional applications by only one 2D materials. 2D materials can be stacked to produce van der Waals heterojunctions with specific functions, and then produce the next generation of functional devices, which has gradually become an important development direction of low-dimensional devices and semiconductor applications. Superlattices or van der Waals heterojunctions of graphene, hexagonal boron nitride (hBN) and other 2D materials, which are stacked by stripping method, can exhibit different properties such as unconventional superconductivity, anomalous quantum Hall effect, and ferroelectricity under different rotation angles. This talk mainly introduces our two recently proposed methods of stacking growth and stacking transfer for the preparation of wafer-level, high-quality 2D materials van der Waals heterojunctions, including graphene, hBN, 2D semiconductors, metals, superconductors, ferromagnets, etc., and initially explores the functional applications of 2D materials van der Waals heterojunctions.

Libo Gao joined Nanjing University as a Professor of Physics and a Principal Investigator at Nanjing National Laboratory of Microstructures in May 2015. He received his Ph.D. degree in material sciences from Institute of Metal Research, Chinese Academy of Sciences, in 2011. Then he worked at Graphene Research Center, National University of Singapore, as a Research Fellow for four years. His awards include the first class prize of the Liaoning province natural science award 2015, second prize in China's State Natural Science Award, and NR45 Young Innovators Award 2021. He published over 50 papers (with over 1,2000 citations), including 3 Nature papers. His research focuses on chemical vapor deposition growth, characterization and application of different kinds of two-dimensional materials, like graphene, transition metal dichalcogenides, superconducting or quantum materials in two dimension.
