| Research Abstract |
In this research project, we aimed to elucidate ultrafast dynamics of photoinduced structural phase transitions in selected important typical materials, using the state-of-art experimental methods and theoretical methodology. New material phases have been discovered, and relaxation of electronically excited state has been resolved directly at femtosecond temporal domains. The develope a new time-resolved electron diffractometer, which shows outstanding performance, and ultrafast structural dynamics of metals and semiconductors have been revealed from atomic levels.
