| Research Abstract |
Surface structures in lattice mismatch system such as InAs/GaAs are systematically investigated using our ab initio-based approach incorporating beam equivalent pressure and temperature. Adsorption-desorption behaviors of In and As are also clarified on the stable surfaces of InAs(111) and InAs(001) wetting layers under growth conditions. Using these results, elementary processes of nano-structure formation are discussed for stacking fault tetrahedron on InAs(111) and quantum dot on InAs(001) grown on GaAs substrate.
