Recently, Pan Zhao, a postdoctoral fellow of the State Key Laboratory of Refractories and Metallurgy, was co-constructed by the provincial Ministry of our university. His research paper was published in Science. The title of this paper is Giant polarization in super-tetragonal thin films through interphase strain (preparation of ultra-tetragonal thin films with large polarization by interfacial strain). Chen Jun, Professor of University of Science and Technology Beijing and Prof. Xing Xian ran are the authors of correspondence.

Ferroelectric material is an important functional material, widely used in ferroelectric memory, tunable microwave devices, large capacity capacitors, piezoelectric sensors and other fields. In this paper, a new method called Interphase Strain, which can be used to realize strain engineering easily, is proposed. The ferroelectric thin films with the strongest iron electrode strength have been successfully prepared. This phase interface strain method provides a new idea for the design of novel ferroelectrics, and can also be used in the design of other multifunctional materials.

The research work also received the help and cooperation of the University of Texas, Dallas, Tel Aviv University, St Andrews University, Tsinghua University and the Chinese Academy of Sciences.


Dr. Pan Zhao is the 2011 undergraduate graduate of Metallurgical Engineering in our university, and then he studied in Beijing University of Science and Technology. In 2017, he entered the Postdoctoral Station of the State Key Laboratory of Refractory Materials and Metallurgy. The main research areas are functional ceramics, including Perovskite Ferroelectric / piezoelectric materials, negative thermal expansion materials, and thermoelectric conversion materials.


Up to now, Dr. Pan Zhao has published 11 SCI papers in J.Am.Chem.Soc., Inorg.Chem., J.Am.Ceram.Soc., and more than 20 SCI papers in the journals of Sciences, Nat.Commun., Phys.Rev.Lett., J.Mater.Chem.C. (News Centre)
