    摘要: An initial single-crystalline diamond base material is prepared from a flat plate having a major surface and side surfaces consisting of low-index planes. Then, single crystalline diamond is homoepitaxially vapor-deposited on the single-crystalline diamond base material, and a resulting diamond material is cut and polished in a particular manner to provide a successive base material on which single-crystalline diamond is again grown, thereby forming a single-crystalline diamond having a large area. A holder for the single-crystalline diamond base material consists of or is coated with a material hardly forming a compound with carbon. Single crystalline diamond can be stably formed on the surfaces of the base material. Consequently, single-crystalline diamond of high quality having a large area can be stably produced in a shorter time using either plasma CVD or a thermal filament method.

    摘要: Diamond particles are dispersed in a metal and the metal matrix is molten and recrystallized so that the diamond particles are aligned to the same crystal orientation to form a substrate equivalent to a diamond single crystal substrate and then the diamond is grown by a vapor phase synthesis on the substrate. The diamond single crystal having the homogeneity and good quality can be formed and the diamond single crystal having a large area can be easily and economically obtained.

    摘要: In a method of synthesizing diamond on a substrate from plasma containing a carbon component, filaments containing tungsten as a thermoelectron-emitting material are arranged above a substrate in a chamber. An electrode is provided at a position separated from and particularly above the filaments. The filaments are at least temporarily energized with a potential relatively higher than that of the substrate, while the electrode is at least temporarily supplied with a potential relatively higher than that of the filaments. Thus, plasma is generated between the filaments and the substrate, while electrons are moved from the filaments to the electrode for also generating plasma between the filaments and the electrode, thereby forming nuclei of diamond on the substrate. Thereafter, the respective potentials of the electron emitting filaments and the electrode are equalized with each other, for growing a film of diamond from the nuclei of diamond.
