EDUCATION AND RESEARCH EXPERIENCE
Xian-Hui Chen, Professor of physics in University of Science and Technology of China. He was employed as “Changjiang Chair Professor” in 2003. He is mainly engaged in the exploration of new materials: he discovered the new superconductor Sm2.75C60 and a series of new materials such as Sm6C60, K3.25Sm2.75C60, Sm3C70 and Ba3C70 and so on; he synthesized two new series of copper-oxide superconductors (Bi,Sr)2(Ln,Ce)2Cu2Oy and (Bi,M)Sr2(Ln,Ce)nCu2Oy. He has continuously been engaged in the experimental researches on the physical properties in the strongly correlated electron systems. He has made notable research results including the transport properties under magnetic field and interactions between spin structure and charge in the high-temperature superconductors and cobalt oxide, the effect of charge transfer on the phonon behavior in fullerene compounds and the metal-insulator phase transition and spin-state transition induced by the oxygen isotope substitution in the perovskite cobalt oxides. In the last three years, he has made innovative exploration in the new iron-based high-temperature superconducting materials: for the first time he discovered high-temperature superconductivity with TC = 43K in SmFeAsO0.85F0.15, realizing the high-temperature superconductivity in atmospheric pressure for a copper-free material; he pioneered self-flux method to grow the large high-quality single crystals of the iron-based system with 122 structure; he systematically studied the electronic phase diagram for the iron-based superconductors with 1111 and 122 structure and supplied experimental evidences for the coexistence of spin density wave (SDW) and superconductivity in the iron-based superconductors; he is the first to carry out the studies of the effect of oxygen and iron isotope substitution on the superconducting transition temperature and SDW transition temperature in SmFeAsO1-xFx and Ba1-xKxFe2As2 systems and found a large iron isotope effect, which is crucial for comprehensively understanding the mechanism of high temperature superconductivity. He has authored and co-authored more than 240 refereed journal publications, including 3 in Nature, 3 in Nature Materials, 1 in Nature Physics, 23 in Physical Review Letters, 3 in Journal of American Chemical Society and more than 60 in Physical Review B. These articles have been cited by more than 3600 times totally.
In 1998, he achieved “National Science Fund for Distinguished Young Scholars of China” from National Natural Science Foundation. His recent awards include "Changjiang Scholars Achievement Award" from Ministry of Education (2009), “Outstanding Science &Technology Team Achievement Award” from Hong Kong Qiu Shi Science and Technologies Foundation (2009), “Ye Qisun Physics Prize” from Chinese Physical Society (2008-2009), “The First Prize of Science & Technology in Scientific Research for Colleges and Universities” (2010), “The First Prize of Science and Technology in Anhui province” (2010) and so on.
