We report on the morphological study of focused ion beam (FIB) milling of both sputter-deposited and single crystal (0001) ZnO substrates. The surface roughness and the FIB induced sputtering yield were measured as a function of the ion dose and angle. Smoothing effect of rough films deposited by sputtering has been found at low ion doses. FIB milling at non-normal incidence produced roughness increase and the formation of ordered terraces on (0001)-oriented sputtered ZnO. Conversely, surface roughness and FIB yield on single crystal ZnO substrates is basically unaffected by ion dose and milling angle.

Abstract
We report on the morphological study of focused ion beam (FIB) milling of both sputter-deposited and single crystal (0001) ZnO substrates. The surface roughness and the FIB induced sputtering yield were measured as a function of the ion dose and angle. Smoothing effect of rough films deposited by sputtering has been found at low ion doses. FIB milling at non-normal incidence produced roughness increase and the formation of ordered terraces on (0001)-oriented sputtered ZnO. Conversely, surface roughness and FIB yield on single crystal ZnO substrates is basically unaffected by ion dose and milling angle.File in questo prodotto:
