Schematic images of the process of FIB pre-milling with the following thermal evaporation. (a) Cross section of the nanostructures before and after thermal evaporation. We can clearly find that the spacing becomes smaller after depositing gold film; (b) top view of the nanostructures. It describes the change of the nanostructures’ morphology.
