| Research Abstract |
The main object of the project is to make improvements of the organosilicon ion beam technology and to use its beam for SiC heteroepitaxy research, including some spin-off effects of the ion beam technology to other field. The object has been divided into three things, and the research results follow those
(1) Reduction of fast neutrals included in the decerelated ion beam.
Introduction of a quadrapole imaging system and a graphite beam aperture has attained the reduction of fast neutrals containment from 2% to 0.5% and also the increase of beam current density by a factor2. (Papers in preparation)
(2) Reduction of deposition temperature and the beam energy dependence of crystallization
In 100eV SiC heterpepitaxial growth, the temperature of the target Si wafer has been lowered to 500℃. In the deposition experiment with beam energy between 10 and 100eV, it is found that the transition of the crystallized characteristics changes from 4H-SiC to 3C-SiC(001). (Papers in preparation)
(3) Spin-off experiment of the ion beam technology We have tried C^+ beam deposition on the Si wafer without any diamond nucleolus at the liquid nitrogen temperature, but this has not been succeeded yet. An application of the technique to a high temperature plasma experiment. Using other ion sources, the beam injection experiment has been done to FRC plasma, successfully
