Recently, the review articleRecent Progress in the Fabrication, Properties, and Devices of Heterostructures Based on 2D Materialswritten by Zhang Siyu, a undergraduate enrolled at School of Physics and Electronics of CSU in 2015, was published in the high-level SCI journalNano-Micro Letters(IF:7.381, Zone 1 of Chinese Academy of Sciences JCR). Zhang Siyu and her advisor Liu Yanping are co-first authors of this article, and CSU is the first unit.

In addition to the advantages of 2D material itself, the heterojunction in 2D materials has the characteristics that the single 2D materials and the heterojunction in traditional block materials lack, such as interlayer excitons with longer life, flexible energy-band engineering and enhancement of valley polarization. Therefore, the heterojunction in 2D materials is undoubtedly a key component of the new generation of optoelectronic devices, valley electronic devices and self-spinning devices, and has a broad application prospect. With the continuous development of such preparation technologies of heterojunction in 2D materials as dry transfer and CVD synthesis, the researches on its various physical properties have been gradually deepened. This review article summarizes the research results of preparation, energy-band structure, exciton characteristics, transport properties and magnetic properties and other aspects of heterojunction in 2D materials, as well as its application in optoelectronic devices, valley electronic devices and self-spinning devices in a comprehensively way; it points out the main challenges arising in universal application of 2D material heterojunction devices, and puts forward the design though of future heterostructure and the development trend of this field.
Zhang Siyu joined the low-dimensional quantum device laboratory of CSU in her junior year. Under the guidance of Professor Liu Yanping, she carried out literature study and collection, picture processing and writing, which took 8 months. This paper is the one with the highest impact factor among the SCI papers published by undergraduates ofSchool of Physics and Electronics. Meanwhile, her work in paper writing has been strongly supported by the Natural Science Foundation of China, Innovation-Driven Program of CSU and Youth Innovation Team of CSU. At present, two other SCI papers on scientific research experiments of Zhang Siyu are under review, and she is expected to publish three high-level SCI papers before graduation.
