| Research Abstract |
We have reported that epitaxial growth mode of thin metallic films on the Hydrogen-terminated Si surfaces were slightly different from that on the clean Si surfaces. Our subject on this research project supported by a Grant-in-Aid for Scientific Research is to develop a new hydrogen analysis technique by combined the classical methods and apply to the real hydrogen-silicon systems. The new findings are as follows.
(1) Combining the low energy electron diffraction (LEED) and the low energy ion scattering (ISS) containing detection of the absolute volume of hydrogen using the recoil detection system causes the powerful tool to investigate the hydrogen induced epitaxy. We also used the STM for the ex-situ observation of surface morphology.
(2) Not only MBE methods but also sputtering methods were applied to make metal epitaxial films on Si substrates to investigate the role of hydrogen on the films.
(3) Initial stage of 2-dimensional superlattice induced by specific materials such as Ag, Pb and In changes to 3-dimensional intrinsic cluster growth after the Hydrogen termination.
These results cause the key of better understanding of modification of heteroepitaxy by the Hydrogen termination.
