Interface mixing induced by energetic ions is discussed, applying the author's thermal spike model. Diffusion in the ion-induced melt is assumed. An expression is derived for the variation of the mixing rate k with the electronic stopping power S[sub e]. The experimental results recently reported by the Stuttgart group on NiO, ZnO, CuO, and Cu[sub 2]O layers on SiO[sub 2] substrate are analyzed and good agreement is found with the predictions of the model for k and for the threshold of S[sub e] for melt formation. Average diffusion coefficients in the spike are estimated, and D[sub d]≈0.053, 0.03, and 0.004 cm²/s are obtained for Zn, Ni, and Cu ions, respectively.

    As already noted by Behar et al. in the nineties, the penetration depth of heavy ions into light targets is often much larger than predicted by Ziegler's SRIM (The Stopping and Range of Ions in Matter) program. Evidently, SRIM stopping power must be too high at low energy in these cases. This...
