Research fields and main achievements:
Professor Yuan is a young scientist active in such areas as new field-effect devices, novel hetero-interfaces and low temperature physical and electronic transport. He has achieved outstanding results in the design and development of solution-gated field-effect transistor devices and low temperature electron transport.
Ionic liquids can form an electric double layer structure on the semiconductor surface under gate voltage. On this basis, Yuan developed an electric-double-layer transistor prototype device using ionic liquid as the dielectric material, which has achieved high performance, low power consumption and high conductivity field-effect transistors on a variety of semiconductor materials. Furthermore, he applied this prototype device to strongly correlated materials and other quantum material systems, resulting in various field effect-induced novel interface physical phenomena, such as field-effect-induced superconductor–insulator transition, paramagnetic-ferromagnetic phase transition, spin polarization and the generation and regulation of spin photocurrent. The electric field modulation of electrical double-layer structure has attracted the attention of many colleagues at home and abroad.
As a member of Xue Qikun’s research group, Professor Yuan earned his doctorate in 2007 from the Institute of Physics, Chinese Academy of Sciences. Upon graduation, he started postdoctoral research in Iwasa Hiroshi’s research group at Tohoku University. From 2010 to 2012, he transferred with Iwasa’s research group to the Department of Applied Physics and Quantum Phase Electronics Research Center of University of Tokyo. During this period, he served as an assistant researcher and then assistant professor at the university. In early 2012, he joined the research group of Cui Yi and Harold Hwang at Stanford University. He worked as an assistant researcher and then SLAC Associate Staff Scientist and engaged in field-effect modulation of the physical properties of two-dimensional quantum systems. In 2017, he was selected into the Overseas Young Scholars Project of China and was appointed a professor and doctoral supervisor at the College of Engineering and Applied Sciences, Nanjing University.
As of April 2019, Yuan has published over 80 articles on high impact-factor journals, including 17 on Science and Nature series journals (1 on Science, 8 on Nature Nanotechnology, 1 on Nature Materials, 1 on Nature Physics, 5 on Nature Communications) and 3 invited review papers, with a total of more than 6,000 citations and an H-index of 34. He holds 18 international and Chinese patents. He was invited to speak on more than 20 famous international conferences including APS, MRS, ECS and MMM annual conferences. He is currently a special reviewer for journals such as Nature, Nature Nanotechnology, Nature Physics, and Nature Communications.
