Biography

Yao Xi, male, Han nationality, is a native of Suzhou, Jiangsu Province. He graduated from Jiaotong University and received a doctorate from Pennsylvania State University.

Yao spent his career as a professor at Xi'an Jiaotong University and Tongji University. He mainly engaged in research concerning electronic ceramic material and components. One of his achievements in his research of bicrystal and multicrystal interface, is that he found piezoelectric resonance phenomenon in ceramic crystal grain. By adopting a computer circuit simulation method, he worked out di-electric spectrum of multicrystal congeries of which grain size and orientation are randomly distributed.

Yao also carried out systematic research on polarization relaxation phenomena in ferroelectrics. He discovered a series of new phenomena, such as microdomain-macrodomain transition, electric field induction, nanometer structure adjustment and super paraelectric state.

Yao is a member of two international ceramics organizations and a member of the Chinese Academy of Sciences.
