Outline of Final Research Achievements

In this study, we created an electron beam simulated solution plasma and applied it to the surface treatment process. With regard to the former, generation of new field emission dielectric barrier discharge in high density media such as high pressure, liquid and supercritical fluid, voltage / current characteristics, and spectroscopic measurement were conducted to clarify its characteristics. In addition, the calculation simulation revealed the likelihood of qualitative behavior regarding the dependence of the firing voltage on the media generation of the discharge. In addition, by using carbon nanotubes as electrodes, we succeeded in generating stable plasma in a high density environment including supercritical and liquid. In addition, as an application of this plasma process, we succeeded in handling and deposition of fine particles.
