| Outline of Final Research Achievements |
We have demonstrated that a unique nonequilibrium growth method, in which a paste containing tin is screen-printed on a silicon or germanium substrate and then subjected to pulsed laser annealing, can be used to fabricate alloy thin films containing tin that exceed the solubility. In addition, the evaluation by X-ray diffraction and X-ray fluorescence holography showed that tin substitutes the lattice positions. White neutron holography was made highly sensitive, paving the way for the observation of hydrogen atoms passivating defects in semiconductors.
