Abstract

To understand the growth mechanism of electrodeposited Fe, Ni and Co, we have studied the effect of workfunction on the metal nanowire growth by SEM and Potentiostat. We found that the current density for deposition of Fe nanowires is higher than of Ni and Co nanowires under the same fixed potential, overpotential, pH, concentration of metal ions and temperature. Using the electrons tunneling theory, we have argued that the current density of the metals depends on the workfunction and width of double layer. The current density increases with decreasing the length of double layer. The current density of metal with a smaller workfunction can be higher than that of metal with a larger workfunction.
