摘要
40-130 kev Ag** plus ions have been implanted at 46 K and 300 K into Ni films (25-38 nm thick) deposited on NaCl and Ni single crystals (100) and (110) in the dose range 10**1**1 to 4 multiplied by 10**1**6 cm** minus **2. In-situ backscattering measurements and channeling (in the single crystals) have been carried out. The thin films were also analyzed using TEM, STEM and EDS. For the single crystal samples it is found that 80% of the Ag is substitutional at the Ag saturation concentration (7-8 at. % max. concentration). Annealing at 623 K for 1 h, decreases the substitutional fraction to 60%. Bombardment of the thin films at both 46 K and 300 K results in significant recrystallization and grain growth when the ion dose APP GRTH 10**1**5 cm** minus **2.
