Particles with Intelligent Characters: Chaotic Motion of Electrons in Semiconductors

Speaker:Prof. Xue-Chu She
Affiliation:Institute of Technical Physics, Chinese Academy of Sciences Department of Physics, Fudan University
Date:December 10, 2010
Time:5:00 - 6:30 p.m.
Venue:Lecture Theatre P3, Chong Yuet Ming Physics Building



We are in an information era. Electrons appear everywhere in our life. After a brief review of the history of the discovery of the electron and its duality characters, I will discuss our recent experiments on the chaotic motion of electrons related to the impurity center in the semiconductors and in the anisotropic solid state environments. The chaotic behavior of electrons is revealed and confirmed by the quasi-Landau resonance in the ionization spectroscopy of the impurity, and by abnormal energy level spacing distribution, which are related to the Kepler problem several hundreds year ago.

About the Speaker:

Prof. Shen is a leading expert in infrared optical experiments. He is a Member of Chinese Academy of Sciences. Among the numerous awards he has received, include Kenneth J Button Prize for the sciences of magneto-electrical Spectrum in 2006, and Ho-Liang-HoLee Award for Physical Science in 2002. He is a member of editorial board of many journals and the Dean of College of Sciences, Shanghai University.
Physics colloquium series is organized to introduce cutting edge researches and new development in physics, designed to be suitable to graduate and undergraduate students, and also to scientists working on different fields. Each colloquium will generally start with an extensive introduction of the background of the field, followed by forefront research topics and results. The colloquium will serve as an education forum for students and laymen alike, and also serve as a platform for exchange and update their knowledge of various branches of physics among academic staff members.
