介面控制下的自主化成長

The focused research of nano-science and nano-technology area for the entire world has been preceded for over 10 years. Many results have been addressed and shown the devices based the nanostructures will match the new topic—green energy. As the smaller and smaller is the material structure, the greater and greater is the percentage of the surface atoms and the more and more important is the surface property. The most important mission for nanoscience now should be to study the nanostructure properties by surface analysis techniques at atomic scale. This is a one-year research project. In this project, we have investigated the self-assembly growth under the interface control by STM and FIM. In this year, we have finished the study of the ultra-sharp Pd, Pt, Rh, and Ir covered Mo and pure Mo single atom tips and try to study the Si growth on different facets of Ir and Pt by FIM. Using scanning tunneling microscope, we have studied the growth behavior of Fe islands on Ge(111) and Ag/Ge (111) surfaces. The results have been written as papers and submitted.
