    Abstract: A light emitting device using a silicon (Si) nanocrystalline Si insulating film is presented with an associated fabrication method. The method provides a doped semiconductor or metal bottom electrode. Using a high density plasma-enhanced chemical vapor deposition (HDPECVD) process, a Si insulator film is deposited overlying the semiconductor electrode, having a thickness in a range of 30 to 200 nanometers (nm). For example, the film may be SiOx, where X is less than 2, Si3Nx, where X is less than 4, or SiCx, where X is less than 1. The Si insulating film is annealed, and as a result, Si nanocrystals are formed in the film. Then, a transparent metal electrode is formed overlying the Si insulator film. An annealed Si nanocrystalline SiOx film has a turn-on voltage of less than 20 volts, as defined with respect to a surface emission power of greater than 0.03 watt per square meter.
