Invited by our university, academician Kai Chang from the Institute of Semiconductors, Chinese Academy of Sciences attended the Ninth Lecture of the Truth-Seeking Forum in the Institute of Fusion Innovation on the afternoon of June 23, and gave a lecture titled "Quantum Phase in Low Dimensional Semiconductors" at the Jianlong Lecture Hall. Prof. Luning Wang, Vice President of the university attended the lecture, which was hosted by Prof. Rongming Wang.

Qingguo Xue Meeting with Kai Chang

Before the meeting, Vice President Qingguo Xue expressed a warm welcome to the visit of Academician Chang on behalf of the university and they had an in-depth exchange on some topics, such as talent training, scientific research, discipline construction and so on.

Kai Chang Giving his Lecture

Kai Chang is a senior researcher of the Institute of Semiconductors, Chinese Academy of Sciences who was not only elected into the “100-Talent Plan” of CAS in 2000 but also an winner who ranked the third in the Second Prize of National Natural Science of China in 2004. He was awarded the 2005 Distinguished Youth Fund, won the Huang Kun Scientific Award on Solid State Physics and Semiconductor Physics of Chinese Physical Society in 2013, and was elected as member of the Division of Mathematical Sciences of CAS in 2019. He has long committed himself to the fundamental research in semiconductor physics, and served as Chairman of the 17th Conference on Narrow Energy Gap Semiconductor Physics as well as President of the Program Committee of the 33rd International Conference on the Physics of Semiconductors (ICPS-33) in 2016.

In the Lecture

In his lecture, Mr Chang vividly and interestingly illustrated various evolutionary canonical fields and their induced novel quantum effects presented in semiconductor quantum structures in recent years to the audience in conjunction with his own research. He began by explaining that semiconductor quantum structures had shown many novel physical phenomena in the past four decades. Then he reviewed the application values of semiconductors, which have realized our applicating of many important practical devices. Finally, he suggested that semiconductors are also an excellent experimental subject for exploring all kinds of evolutionary canonical fields and their associated quantum effects, which can combine dimensional effects, correlation effects and energy band topological properties to study new quantum phases resulted from the interaction of these effects.
