Outline of Final Research Achievements

Surface stress processes reveal nature of growth stages during nano-structural formation. We focused on time evolution of the stress during surfactant-mediated epitaxy and reconstruction. Real-time observations of the stress/strain and morphology were performed simultaneously by using substrate curvature and electron diffraction methods. As a result, we have found a direct evidence for stress of reconstruction. Furthermore, the real-time stress measurement has provided a unique stress evolution during the nano-structure growth. We have realized a stress induced system for fabrication of nano-structures.
