Application of Femtosecond Spectroscopy to Materials Science
Dr. K. Ishioka (ANCC Ultrafast Spectroscopy Group)
-
Opt-electronics is one of the key technologies both in our daily life
and in the next-generation innovation. The elementary process to convert light to electric current in semiconductors takes place within femtoseconds, and the following transport and recombination processes in pico- to microseconds, depending on the material and its dimension. To design new materials for faster and more efficient opt-electronics it is essential to know their ultrafast photo-response in detail. In this talk I will first overview the experimental technique
of the femtosecond spectroscopy, especially of “coherent phonon spectroscopy”, and then give a few example of its application to solid state physics and materials science.
