The highly-oriented diamond films are grown by chemical vapor deposition and at least 80% of the surface area of said diamond film consists of either (100) or (111) crystal planes, and the differences {.DELTA..alpha., .DELTA..beta., .DELTA..gamma.} of Euler angles {.alpha., .beta., .gamma.}, which represent the orientations of the crystals simultaneously satisfy the following relations: .vertline..DELTA..alpha..vertline..ltoreq.5.degree., .vertline..DELTA..beta..vertline..ltoreq.5.degree. and .vertline..DELTA..gamma..vertline.5.degree. between adjacent crystal planes. The diamond hetero-junction rectifying element thus made has a high rectification ratio and heat resistance, and is suitable for mass production at low cost and on large scale.

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.

摘要： A semiconducting diamond electroluminescence element comprises an electrically conductive substrate, a semiconducting diamond layer formed on the substrate, an insulating diamond layer formed on the semiconducting diamond layer, a front electrode formed on the insulating diamond layer, and a back electrode formed on the conductive substrate in ohmic contact with the same. The color of light to be emitted by the semiconducting diamond electroluminescence element can readily be determined by changing the impurity content in the semiconducting diamond layer. The luminescence intensity of the semiconducting diamond electroluminescence element can readily be changed by changing the voltage applied across the front and back electrodes without entailing dielectric breakdown.
