For many years, the investigation of group-III metals on Si surfaces has been one of the typical studies in surface science. This system exhibits an abundance of surface structures depending on the coverage and the annealing process. Al is one of the group-III metals and a particularly important material for the device applications. But atomic structure of the low-coverage Al absorbed on Si(001) surface is still under debate. Thus, initial stages of Al growth on Si(001) surface have been studied using low-energy electron diffraction (LEED) and coaxial impact collision ion scattering spectroscopy (CAICISS). Because the low energy ion which is sent to the target material from ion source does not deeply penetrate the sample, CAICISS has been known the very surface-sensitive technique.
