He is currently a professor of physics at the Chinese University of Hong Kong. Meanwhile, Professor Xiao has been a visiting professor at China University of Science and Technology since 2004. Professor Xiao has been engaged in the research of surface/interface physics such as metal, semiconductor and thin film physics for more than 20 years, and has published more than 80 papers, including two in Science and nine in Physical Review Letters. His paper has been cited by peers for more than 1800 times. Professor Xiao has won many honors such as "Outstanding Young Scholar" and "Famous Overseas Scholar" of China Academy of Sciences. He also holds two American technology patents. His research involves surface structure, surface adsorption, surface film growth and electronic and mechanical properties of surfaces and interfaces. In recent years, his research team has solved a series of basic scientific problems in schottky junction's work on semiconductor/metal interface, laying a good foundation for its application in photovoltaic solar cells, such as preparing metal electrodes on semiconductor thin films.
In 2008, under the framework of the cooperation agreement between the Chinese University of Hong Kong and China Academy of Sciences, Professor Xiao Xudong and Professor Hakodate set up a photovoltaic solar energy research center in the Institute of Integrated Technology of Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences. Professor Xiao Xudong is the director of the center, and he came to work in Shenzhen Institute full-time on 201/kloc-0. With the strong support of the Institute of Advanced Technology, the Photovoltaic Center has successfully carried out the research on the technology and related equipment of copper indium gallium selenide solar cell through two years' work, accumulated rich experience in the design and manufacture of copper indium gallium selenide related equipment, deeply understood the special requirements of the equipment for the technology of copper indium gallium selenide solar cell, and mastered the equipment law of large-area evaporation coating, which laid a good theoretical and practical foundation for further research and development of large-area copper indium gallium selenide growth equipment based on linear evaporator. Photovoltaic Center successfully completed the project of "evaporation-magnetron sputtering growth system for copper indium gallium selenide thin film solar cells" supported by Chinese Academy of Sciences. Experts from the acceptance team spoke highly of the project results, saying that it "marks the significant progress in the research of high-efficiency thin film batteries in China and provides a technical basis for further promoting the industrialization of copper indium gallium selenide thin film batteries."

Representative achievement
Major academic contributions
1) Based on the domestic technology, the copper indium gallium selenide thin film solar cell equipment with industrialization prospect was developed, and the solar cell with photoelectric conversion efficiency of 17% was successfully prepared in a short time, and the module efficiency exceeded 12.6%. The related technology reached the domestic leading level and was also the world-class level;
2) Using STM tunneling spectrum, it is found that conventional superconductors have pseudo-gap states similar to high-temperature superconductors in nanometer scale;
3) Using STM to study the nanotunnel junction, the phenomenon of quantum capacitance is confirmed experimentally for the first time, which is of great guiding significance to the construction of nanotunnel structure in nanoelectronic devices;
4) Tribology is studied by atomic force microscope, especially the friction force at atomic scale is measured quantitatively, and the relationship between the order of organic monomolecular configuration and lubrication is found, which is of great significance to understand the microscopic mechanism of friction force and its application field. Combined with theoretical calculation, the friction and adhesion of C60 single crystal surface near ordered/disordered phase transition are quantitatively studied, and it is proved that the degree of freedom of C60 rotation has no effect on energy dissipation.
5) Co-invented the scanning polarizing microscope, and found for the first time that the water film formed on mica surface at room temperature has an "ice-like" structure. This achievement has deepened people's understanding of "water" and triggered and stimulated a series of theoretical and experimental work in this field.
6) The linear optical diffraction is used to study the surface diffusion for the first time, and the relationship between the anisotropy of diffusion, surface coverage and impurity effect is successfully studied, thus solving the long-term problem of surface diffusion measurement; A new model for measuring surface diffusion of single atom/molecule based on STM is developed, and the formation and interaction of metal/semiconductor interface are deeply studied.

Xinhuanet: Shenzhen and Hong Kong have successfully developed a new generation of solar cells.
Xinhuanet Shenzhen, June 6 (Reporter Wang Pan) The scientific research cooperation between Shenzhen and Hong Kong, which enjoys * * * resources and complementary advantages, has begun to enter the harvest period. With the support of the governments of Shenzhen and Hong Kong, the Chinese University of Hong Kong and Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences have recently successfully developed a copper indium gallium selenide (CIGS) thin film solar cell with photoelectric conversion efficiency of 17%, which is in a leading position in China.
CIGS battery is based on cheap glass, plastic and metal foil, and then plated with 1/200mm multilayer film material, which can generate electricity in cloudy days and scattered light, and is suitable for urban environment with many tall buildings. Compared with the traditional crystalline silicon solar cell, it is 98% thinner and its cost is reduced by half, so it is called "a promising new thin-film solar cell for the next generation".
CIGS battery developed jointly by Shenzhen and Hong Kong is slim, portable and stable. It is not only suitable for building roofs and external walls to generate electricity, but also can be implanted with personal items such as handbags and backpacks to charge electronic products in real time, and can also be used as a power supply for aerospace and military electronic equipment.
It is understood that this research project lasted for two years, and my colleagues were funded by the Chinese University of Hong Kong, the Hong Kong Innovation and Technology Commission, the China Academy of Sciences and the Shenzhen Municipal Government to develop it in the Chinese University of Hong Kong and the Shenzhen Institute of Advanced Studies.
