Blue–green to near-IR switching electroluminescence from Si-rich silicon oxide/nitride bilayer structures

Abstract

Blue–green to near-IR switching electroluminescence (EL) has been achieved in a metal-oxide-semiconductor light emitting device, where the dielectric has been replaced by a Si-rich silicon oxide/nitride bilayer structure. To form Si nanostructures, the layers were implanted with Si ions at high energy, resulting in a Si excess of 19%, and subsequently annealed at 1000°C. Transmission electron microscopy and EL studies allowed ascribing the blue–green emission to the Si nitride related defects and the near-IR band with the emission of the Si-nanoclusters embedded into the SiO2 layer. Charge transport analysis is reported and allows for identifying the origin of this two-wavelength switching effect.
