• to diffraction was observed [15]. Properties of the Au, Ag, and Cu nanostructures and also bi-metal nanosystems (known for broader tunability) such as Au/Ag and Au/Ni were reported in a number of papers where the keyword “laser nanostructuring” (or annealing) is used rather than “laser dewetting” [16

• ][17][18]. It should be understood that laser dewetting refers to a physical phenomenon resulting from rapid heating and cooling while nanostructuring is a technological process characterized by nanoscale morphology. Therefore, the equivalent use of both terms is justified by the same underlying basic
