Research Abstract

A novel time-resolved electron diffraction has been developed by combining a reflection high-energy electron diffraction (a technique for surface structure) and a streak camera (a method for ultrafast phenomena). Using the developed method, we have successfully observed the structural transition of Si(111) 7x7 surface by the irradiation of nano-seconds pulse laser with the temporal resolution of 1 micro-second.
