| Research Abstract |
Various shapes of ZnO, CdO, MgO and SnO_2 nanostructures were successfully grown by the atmospheric-pressure CVD (AP-CVD) utilizing catalyst materials. Especially the ZnO and CdO nanorods grown at high substrate temperatures exhibited tapered shapes, resulting from the competition between the vapor-liquid-solid (VLS) and the vapor-solid mechanisms. The alternate supply of Zn and H_2O was found to be effective for suppressing the tapering of ZnO nanorods. Moreover, Cu-Ga-O films grown by the AP-CVD method, one of the possible candidates for the shell layer in core/shell structures, showed strong yellow luminescence.
