    摘要: A method is presented to manufacture substrates for growing monocrystalline diamond films by chemical vapor deposition (CVD) on large area at low cost. The substrate materials are either Pt or its alloys, which have been subject to a single or multiple cycle of cleaning, roller press, and high temperature annealing processes to make the thickness of the substrate materials to 0.5 mm or less, or most preferably to 0.2 mm or less, so that either (111) crystal surfaces or inclined crystal surfaces with angular deviations within .+-.10 degrees from (111), or both, appear on the entire surfaces or at least part of the surfaces of the substrates. The annealing is carried out at a temperature above 800.degree. C. The present invention will make it possible to markedly improve various characteristics of diamond films, and hence put them into practical use.

    摘要: A diamond Schottky diode including an electrically conductive substrate, a multi-layer structure of a semiconducting diamond layer and an insulating diamond layer, and a metal electrode. This diode has a greater potential barrier under a reversed bias and hence exhibits better rectifying characteristics with a smaller reverse current.

    摘要: A diamond light-emitting element capable of intense light emission at low operation voltage. A conductive substrate is disposed on a metallic plate such as copper to form an ohmic contact. A first diamond layer is formed on the conductive substrate. The boron atom concentration in the first diamond layer is 10.sup.19 cm.sup.-3 or higher. A second diamond layer is formed on the first diamond layer. The second diamond layer has a crystal defect density of 10.sup.11 cm.sup.-2 or higher. A second electrode is formed on the second diamond layer. A power supply is connected to the second electrode and the copper plate. When voltage is applied, holes in the first diamond layer recombine with electrons from the second electrode, and hence light emission takes place. The defect levels in the second diamond layer form the recombination centers to achieve high brightness at low operation voltage.
