We studied the effect of RTP and furnace annealing on the transport properties and electroluminescence of Si-nc embedded in SiO2 layers, and of Er ions coupled to Si-nc. The light emitting devices have been fabricated in a CMOS line by implantation of Si and Er in SiO2. The results show that for the same annealing temperature, furnace annealing decreases electrical conductivity and increases probability of impact excitation, which leads to an improved external quantum efficiency. Correlations between phenomenological transport models, annealing regimes, and erbium electroluminescence are observed and discussed.
