Research Interests：Have been engaged in low-temperature physics and superconductivity research especially in searching for high temperature superconductors since 1976. More than 170 papers have been published. His group discovered independently the liquid nitrogen temperature superconductor and firstly announced its chemical composition of Ba-Y-Cu-O to the world in February 1987. This study has promoted the superconductivity research in many countries. He and his foreign collaborators have been studying intrinsic inhomogeneity and phase separation in cuprates since 1994 and found magic doping phenomena as well as intrinsic electronic phases which are closely related to the mechanism. In 2008, his research team,via applying high-pressure synthesis method, upgraded the superconducting critical temperature above 50K for the first time by substituting Pr for La and created the highest Tc record of 55K. A series of fluorine-free hypoxia superconductors have been synthesized by high-pressure synthesis method for the first time. A series of fluorine-free iron-based superconductors with substituting heavy-rare-earth elements for La have been synthesized by high-pressure synthesis and quenching methods for the first time. Current research interests include discovering new superconductors and investigating the mechanism of novel materials especially the high-temperature superconductors.
