Pulsed Irradiation

ABSTRACTStructural modifications in nanocrystalline silicon-silicon dioxide (nc-Si/SiO2) superlattices (SL) under high intensity laser irradiation have been studied experimentally and theoretically. The melting threshold in nc-Si/SiO2 SLs was found in the range of 5–8 kW/cm2 for cw excitation by 514 nm line of Ar+ laser and ∼11–15 mJ/cm2 for pulsed irradiation by 248 nm, π∼20 ns KrF laser. The irradiation of the samples above the melting threshold induces the irreversible modification of nc-Si layers, which is controlled by the thickness of the separating SiO2 layers, and increases the PL intensity increases by more than 300%.

Model Calculations

On the basis of a weak-coupling model, adjustments are made to the interactions used in the full shell model calculations of Millener in order to fit the experimental energies of the low-lying negativeparity levels of 16N and of the low-lying positive-parity levels of 180 and 190 . The predicted energies of the low-lying negative-parity levels of 17N then agree better with experiment, while those for 18N lead to suggested spin assignments for the observed levels.
