“…Various methods for the deposition of ZrO2 thin layers have been applied, such as sputter deposition, electron beam deposition 2) , plasma 3) and ion beam 4) deposition, sol-gel processing 5) , and chemical vapor deposition. Among them, the sputter deposition technique has been widely used to achieve metallic oxides with homogeneity, good uniformity, and low deposition temperature 6,7) . The elementary event in sputter deposition is an atomic collision cascade.…”
