| Outline of Final Research Achievements |
Because a refractive index of cubic silicon carbide (3C-SiC) is relatively high and a reflectance of SiC is about 20%, SiC cannot become the dark material which is near to a perfectly black body. In this study, we challenged a product of dark material made by the SiC films. The polycrystalline SiC film that the surface was black was deposited by chemical vapor deposition using organosilane gas. By optimizing the conditions of SiC growth, we succeeded in the development of polycrystalline SiC film with a low-reflectance of about 6% in an ultraviolet, visible, and near-infrared light range.
