| Research Abstract |
In this research, the initial growth process of the iron silicide nano islands on Si(111) was studied by the low-energy electron microscopy (LEEM) with high spatial resolution.
From the LEEM images at several growth phases of several growth methods, the incident electron energy dependences of the low-energy electron diffraction (LEED) intensity were directly extracted and the dynamical analyses of LEED were performed.
The practical spatial resolution of the structure determination was about 50 nm. The LEED intensity of a half order spot in addition to the (0,0) spot with the incident electron energy range from 0 eV to 100 eV was obtained, which enables precise determination of the surface structure of small area (about several hundred square nm).
