<p>The invention provides a method of producing a semiconductor diode, which can be a light emitting diode or a photovoltaic cell. A p-type diamond substrate which can be a crystal (10) or a crystalline or polycrystalline film (26) is implanted with ions, preferably at a low temperature, to create a vacancy and interstitial-rich implanted region. The implanted region defines a p-n junction with the substrate. Respective electrical contacts (14, 16; 28, 32) are applied to the implanted region and to the substrate. LED's produced by the method emit blue light, which is useful in telecommunications systems. Photovoltaic cells with a diameter of 50 to 75 mm can also be created.</p> |
