Lithium is ion implanted into a very thin surface layer (106cm)

Lithium is ion implanted into a very thin surface layer (106cm) on a nickel substrate. After implantation, the lithium has a concentration of 1020 atoms /cm3. If the interdiffusion coefficient of lithium in nickel is 5.7108cm2/s at 1000C, determine the time required to reduce the surface concentration to 1018 atoms /cm3
