METHOD FOR PRODUCING BORON-DOPED DIAMOND, BORON-DOPED DIAMOND, AND ELECTRODE

摘要

PPROBLEM TO BE SOLVED: To provide a method for producing boron-doped diamond by which boron-doped diamond particles can be easily produced, to provide a boron-doped diamond, and to provide an electrode. PSOLUTION: The method for producing the boron-doped diamond is characterized in that the boron-doped diamond is grown on the surface of a substrate, where tungsten or its oxide is exposed at least a portion of the surface. The surface roughness of the substrate is preferably 0.5 m. As the substrate, a substrate wherein areas composed of tungsten or its oxide and areas free of tungsten exist in a mixed state can be used. PCOPYRIGHT: (C)2010,JPO&INPIT
