Outline of Final Research Achievements

The object of this study is to prepare crystal substrates with the well-flattened surface and controlled surface composition for epitaxial thin film growth by using the ion beam-induced crystallization. The atomically flattened and well-crystallized TiO2(110) crystals with the surface composition of Sn0.126Ti0.874O2 was obtained by Sn+ ion-implantation at 823K with an energy of 50keV and a fluence of 2E21 ions/m2. It was found that one tenth of implanted ions were contributed to modify the surface composition and the remains were diffused to deeper part of the crystal than that predicted by the conventional theory.
