Recently, it has become very important to obtain knowledge about interactions between substrates and deposited materials in an atomic scale. In this study, we focused on the interaction between Si substrates and Mn particles, which is thought to be important for the fabrication of diluted magnetic semiconductors in which the ferromagnetic atoms are dispersed in the crystalline semiconductor lattice. A sample were prepared by depositing the Mn particles onto a cleaned Si(111) substrate by the PLD method and the observation was performed with a scanning tunneling microscope (STM). First, we have observed size and shape of the adsorbed particles at room temperature. Next, we observed the change of the STM image at elevated temperature up to 200℃. In this paper, we have discussed about the structure of clustered Mn particles on Si(111) substrate by comparing the result with Au particles.
