Formation of High Density ⟨111⟩ Textured Nanotwins in Evaporated Ag Thin Films Through Post-Deposition Ion Bombardment

For the production of Ag thin films containing a high density of nanotwins, evaporated Ag films were bombarded with an Ar+ ion beam with voltage of about 0.1 KeV. After the post-evaporation ion bombardment for 15 min, the equiaxial coarse grains in the surface region of the originally as-evaporated Ag films transformed into slender nanotwinned columns containing a highly More
