Islands of InAs were fabricated at various temperatures by Stranski–Krastanow growth of the molecular beam epitaxy and were observed by the atomic force microscopy. The island size increased and the island density decreased with an increase in temp

A multilayer structure and a single-layer structure of InAs self-assembled quantum dots were grown by molecular beam epitaxy, and cross-sectional observations were made by transmission electron microscopy. Fringe patterns due to wetting layers in the

The anisotropy of superconductivity in highTc superconductors indicates that it is important to clarify the anisotropies of microscopic properties in these materials. In this work, we observed the anisotropy of the lattice vibration ofEu andCu inBa2E

The tip artifact in atomic force microscopy (AFM) observations of InAs islands was evaluated quantitatively. The islands were grown in the Stranski-Krastanow mode of molecular beam epitaxy. The width and height of the islands were determined using tr

Possibility of substitution of Sn for Cu oxide is investigated by X-ray diffraction and TEM. By firing of mixtures of CuO and SnO2 below 1080 °C, it was clarified that few Sn atoms were substituted for Cu in CuO by conventional method (firing at 900
