“…For Cu/Fe multilayer films under 6 × 10 20 ions/m 2 He irradiation with a layer thickness f less than 5 nm, the density of He bubbles increases with the decrease in layer thickness. This [92], Cu/V [5], Cu/Fe [56], Cu/Co [76], Cu/Zr [84], and Fe/W [3]; and Al/Nb [57] multilayer films after He irradiation with different fluences.…”

“…As mentioned above, reducing the layer thickness can effectively decrease the density of irradiation-induced defects, which is responsible for the suppression of amorphization. This phenomenon exists in many multilayer films, such as Cu/Fe [56], Cu/Co [76], Cu/Zr [84], and Mo/Zr [92]. Figure 10a shows the XRD patterns of Cu/Co multilayer films with different layer thicknesses before and after irradiation [76].…”

“…There is a clear trend of the peak density of He bubbles decreasing with decreasing layer thickness due to the increased interface density. [92], Cu/V [5], Cu/Fe [56], Cu/Co [76], Cu/Zr [84], and Fe/W [3]; and Al/Nb [57] multilayer films after He irradiation with different fluences.…”

“…For multilayer films, the mechanisms of irradiation hardening are distinguished at different layer thicknesses [97]. When the layer thickness of the multilayer films is 5-150 nm, the mechanism of hardening caused by decreasing layer thickness corresponds to the confined layer slip (CLS) model [84,92,124]. Under this circumstance, the gas bubbles in the layers act as barriers to sliding dislocations, leading to irradiation-induced hardening [61,125,126].…”

“…For most multilayer films, such as Cu/Mo [129], Cu/V [5], Cu/Zr [84], Ag/Ni [110], Ag/V [130], Mo/Zr [92], and Fe/W [3], the hardening effect can be alleviated by decreasing the layer thickness, as shown in Figure 13. This tendency corresponds to the relationship between the layer thickness and the density of both irradiation-induced gas bubbles and defects.…”

Multilayer films with high-density layer interfaces have been studied widely because of the unique mechanical and functional properties. Magnetron sputtering is widely chosen to fabricate multilayer films because of the convenience in controlling the microstructure. Essentially, the properties of multilayer films are decided by the microstructure, which could be adjusted by manipulating the deposition parameters, such as deposition temperature, rate, bias, and target–substrate distance, during the sputter process. In this review, the influences of the deposition parameters on the microstructure evolution of the multilayer films have been summarized. Additionally, the impacts of individual layer thickness on the microstructure evolution as well as the irradiation behavior of various multilayer films have been discussed.
