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.
Claims15
A light emitting device comprising:
- a substrate of transparent intrinsic diamond material having a p-type region formed therein;
- a first transparent layer of diamond material deposited over the p-type region and covering at least a portion thereof;
- at least one optically transparent conductive contact on or adjacent to the first transparent layer, said at least one optically transparent conductive contact being transparent to visible light;
- and
- a conductive contact applied to the first p-type region.
