ABSTRACT:
A light emitting electronic device has a substrate of transparent intrinsic diamond material with a p-type region formed in it by implantation of boron ions. Discrete transparent layers of diamond material are deposited over the p-type region, each with different electric characteristics. Transparent conductive contacts are formed above the transparent layers, which are separated by a transparent insulation layer, and a conductive contact is applied to the p-type region of the substrate. The different regions of the device emit different colours of light. Various different embodiments and methods of making the device are described.
