Abstract
Nickel nanowires have been formed by the stationary electrochemical deposition of nickel into mesoporous silicon from the modified Watts bath. The polycrystalline nature of the Ni deposit has been established as well as expansion of its lattice parameter in comparison with bulk nickel. Control of the potential of porous silicon during electrochemical deposition allows to determine the moment of complete filling of pore space with Ni. The maximum achieved filling factor was 67% of the pores. The pore dimensions have been found to define the length and the diameter of the Ni nanowires that have equaled to 10 um and 100-120 nm, respectively. ©The Electrochemical Society.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
