Nanofilms: Structural Features and Nanoindentation Methods

The surface morphology of a gold film on a mica substrate after thermal annealing was studied using a Micro-nano mod scanning tunnel microscope. The study showed that the structural elements of a nanofilm are single crystals with spatial orientation (111). The surface morphology of indium and gold nanofilms on a glass substrate produced by magnetron sputtering has a pronounced fine-grained structure. It is shown that the actual indentation depth of an indium nanofilm can be determined after taking into account the resulting pile-ups and relaxation changes of indentation over time. It was established that the indent in a gold nanofilm can disappear over time due to deformation and mutual absorption of gold nanoparticles. The possibility of creating wire nanotracks by tunnel current on an indium nanofilm is shown.
