SEM ((a) and (b)) and cross-sectional TEM images ((c) and (d)) of patterns created using a 5 keV Ga+ beam at normal incidence, RT and a fluence of 2.0 × 1017 ions/cm2, (a) and (c) FIB irradiation, (b) and (d) broad beam irradiation.

Image of FIG. 5.
FIG. 5.

Snapshot of a simulation of the BS equations at (a) t = 250; (b) t = 1000 using the following parameters: normal incidence of ions, λ = −1, a = 0.25, b = 0.37, c = 1, , η = 0, mesh size 200 × 200 points, spatial step size Δx,y = 1, time steps Δt = 0.01, and a starting surface with white noise. For the simulations we used the coupled equations (Eqs. (40) and (41)) and denomination of parameters according to Ref. 22.
