Immersion deposition of Ni on p-Si (100) blank substrates was carried out in an aqueous NiSO4 solution at a pH value of 8 through displacement reactions. Study of the early deposition stage revealed that incorporation of 2.5 M NH4F in solution promoted Ni nucleation significantly. By adding fluoride...
