Profile

Liu Zhiguo, born in 1943, graduated from the Department of Physics, Nanjing University, in 1966. Beginning in 1980, he studied at the University of Göttingen, Germany, under renowned material physicist P. Haasen, with a focus on phase-change mechanisms and phase-change dynamics. He received his doctoral in science from the University of Göttingen in 1984 and began to work at the Laboratory of Solid State Microstructures, Nanjing University, to this day. He became a professor in 1988 and a doctoral supervisor in 1993, and he is now a member of the expert advisory group in the area of materials of the National Key Basic Research Program (the 973 Program), a member of the expert committee of the Integrated Circuit Material Industry Alliance in China, and a vice editorial board member of the journal Materials Letters. He was once a committee member and vice director in the area of new materials of the National High-Tech R&D Program of China (the 863 Program) during the Ninth and Tenth National Five Year Plans, a standing member of the Supervisory Committee of the National Natural Science Foundation of China, and director of the Solid Defect Specialty of the Chinese Physical Society.

Liu Zhiguo has long been engaged in researching ferroelectric dielectric materials, especially the new-type storer and ferroelectric dielectric films applied in field-effect devices in particular. The project he took charge of, “Research on Several Types of Ferroelectric Films and Matching Oxide Electrode Materials,” was awarded the second prize of the National Natural Science Awards (ranking the first of all winners). Liu has played a pioneering role in the research on high-k gate dielectric materials, multiferroic materials and resistive materials and devices. He has also developed a new method of compounding the most important iron electromagnet bismuth ferrite, and this method has been extensively used. His paper on this method has been cited by others for more than 400 times. He has co-authored 4 books and published over 400 papers which have been cited for over 4,000 times in SCI database. He was invited to speak at international conferences for over 10 times, and he has had over 10 Chinese invention patents and 7 scientific and technological awards on ministerial and provincial levels.

As one of the founders of Nanjing University’s faculty of materials, Liu Zhiguo served as a vice chair and acting chair of the Department of Material Sciences. Liu has made great contributions to the teaching of material science. The manuscript Introduction to Material Sciences, of which Liu was a chief compiler, won the second prize of the 2005 National Teaching Achievement Award (with Liu ranking the third).
