Distribution of pit diameters after (2.25 ± 0.06) MeV He ion irradiation. He ions with this energy have a stopping range of 9.91 µm according to SRIM, which is well above the pit depth expected for our etch conditions. The distribution exhibits a tail towards larger pit diameters, which can be well described by a Langau distribution centered at µL = 0.639 µm with σL = 0.059 µm and ηL = 0.035 µm (continuous line). A pure Gaussian/Landau (dotted/dashed lines) distribution would underestimate/overestimate the tail.
