| Outline of Final Research Achievements |
Layer structured In2Se3 was grown on GaAs(111) and Si(111) as a novel buffer layer for high quality GaAs growth on Si. The twin crystal formation can be suppressed by use of a vicinal substrate. The GaAs layer can be grown epitaxially on the layer structured In2Se3, though the GaAs layer shows island growth and twin crystal formation. In addition, we successfully demonstrated the peeling off of the epitaxial GaAs layer from the substrate by the cleavage of the layer structured In2Se3.
