Fei Li

Fei Li is a Professor in Xi’an Jiaotong University, Xi’an, China. He has served as an associate director of Electronic Materials Research Lab (EMRL) in Xi’an Jiaotong University from Sep 2019 to present.

He received B.Eng in Electronic Science and Technology in 2006, followed by a Ph.D in Microelectronics and Solid State Electronics in 2012, both from Xi’an Jiaotong University, China. After completion of his Ph.D, he joined in EMRL in Xi’an Jiaotong University (Lecturer: July 2012-Marth 2015; Associate professor: April 2015- Sep. 2018). From Oct 2015 to Jun 2018, he worked in Materials Research Institute of the Pennsylvania State University as a post doc/research associate, with co-supervised by Profs. Long-Qing Chen and Thomas R. Shrout. He holds 7 patents and has published more than 90 peer reviewed papers in high-ranking journals, including Nature, Science, Nature Materials, etc. He received the Outstanding Young Investigator Award from the Dielectric Physics Society of China (2018) and Star Ambassador Lectureship Award from the society of IEEE UFFC (2020).

His research mainly focuses on the design, modeling and fabrication of high-performance piezoelectric and ferroelectric materials applied for medical imaging transducers, piezoelectric actuators and sensors. He has made important contributions to the understanding of structure-property relationship and the development of relaxor-ferroelectric crystals and ceramics. Three representative contributions are: (1) identify the origin of ultrahigh piezoelectricity in relaxor-PT crystals at mesoscale, (2) develop high performance relaxor-PT ceramics and crystals with ultrahigh piezoelectric activity, and (3) design of transparent relaxor-PT ferroelectric crystals.
