Outline of Final Research Achievements

An objective of this study is the realization of an innovative synthesis technology of energy carries, such as an ammonia, using emitted electron from diamond with a negative electron affinity. In this study, we have developed a high-quality nitrogen-doped diamond film growth technology as its fundamental technology, and demonstrated a highly efficient electron excitation by visible light irradiation.
