Research Assistant Professor College of Science

Dr. Peng-Lai Gong, born in 1985, received his bachelor's degree in material physics from Sichuan University in 2009, and his doctor's degree in condensed matter physics from the University of Chinese Academy of Sciences in 2016. He then worked as a postdoctoral researcher at the Southern University of Science and Technology, where he worked with Assistant Professor Xingqiang Shi as his cooperative supervisor. In 2018, he became a senior research scholar and then a Research Assistant Professor. At present, he is mainly engaged in theoretical research of condensed matter physics, especially two-dimensional materials. He mainly uses the first-principles method to study the outstanding properties of two-dimensional materials, including topological properties, photoelectric and magnetic properties.

The Department of Physics at Southern University of Science and Technology has been established since 2011. The Department’s commitment is to develop  first-class education and top-notch research in physics. The Department of Physics has been granted authority to award bachelor's degree in Physics and Applied Physics. Moreover, the Department offers long-term joint Master and PhD programmes, in collaboration with other renowned universities, including Peking University, Harbin Institute of Technology, University of Hong Kong, Hong Kong University of Science and Technology, and National University of Singapore. In addition, the Department has established long-term joint post-doctoral workstations with Peking University, Fudan University, Wuhan University and other colleges and universities.

he Department has a current size of 37 academic staff, including 6 chair Professors, 6 Professors, 17 Associate Professors, and 8 Assistant Professors. There are 4 Academicians of the Chinese Academy of Sciences (including joint employment), 2 Distinguished Young Scholar, and 3 “Pengcheng” scholars. All members of our academic staff have study or work experience at top 100 universities in the world. The Department of Physics now offers 4 majors in condensed matter physics, computational physics, theoretical physics and optics, while setting up biological physics, astrophysics and particle physics. The staff members are engaged in frontier researches in the fields of quantum transport and regulation, surface physics, materials physics, computational physics, condensed matter theory, quantum information and quantum computing.

In recent years, our staff members have published many papers in high profile journals, gaining the Department international impact. Our research support totaled more than 220.26 million (CNY), including 49 projects from National Natural Science Foundation of China, 9 projects from Ministry of Science and Technology and Department of Education, 14 projects from Guangdong Natural Science Foundation, and 45 projects from Shenzhen City. Our academic staff have published up to 500 papers in recent years. The journals include "Physics Review Letters", "Nature Communications", "Journal of the American Chemical Society", "Advanced Energy / Functional Materials", "NPG Asia Materials", "Physical Review B" and other academic journals.  Southern University of Science and Technology, carrying historical responsibility of higher education reform in China, is rapidly developing towards the direction of international, high-level, research-oriented university. Keeping pace with the university, the Department of Physics has established a long-term development plan to forge ahead in their endeavor, to enhance its own overall strength both in hardware and software, and to strive to maintain the forward momentum into a world-class physics department at an early date.
