  • Method for Producing Diamond Having Acicular Projection Array Structure on Surface thereof, Diamond Material, Electrode and Electronic Device
    Publication number: 20090258255
    Abstract: A method for producing a diamond having an acicular projection array structure on a surface thereof comprises the step of forming the acicular projection array structure on a surface of a diamond base material by treating the surface of the diamond base material by dry etching using oxygen gas. At least one dopant selected among boron (B), nitrogen (N), aluminum (Al), silicon (Si), phosphorus (P), sulfur (S), copper (Cu), arsenic (As), molybdenum (Mo), platinum (Pt) and gold (Au) is doped with a concentration of 1×1019 atoms/cm3 and more at least in a region near the surface of the diamond base material.
