Abstract: | Depth profiles of fluorine in 19F+implanted LiNbO3 have been accurately measured using the 19F(p, γ)16O resonant nuclear reaction at ER = 872.1 keV, with Γ = 4.2 keV. A proper convolution calculation method was used to extract the true distribution of fluorine from the experimental excitation yield curves. The experimental range distribution parameters, Rp and ΔRp, were compared with those obtained by Monte Carlo simulation using a computer code developed recently in this group and with results obtained using the TRIM90 code. It shows that the experimental Rp values agree with the Monte Carlo simulation values very well, while the experimental ΔRp values are larger than those obtained from the simulations. The simulation with our computer code improves the agreement between the experimental and calculated range straggling, ΔRp. |
