The porous silicon morphology effect on the growth of electrodeposited FeNi alloy

► A cathodic deposition of FeNi thin films are formed on porous Si(n). ► Tubular and granular FeNi thin films were obtained and depending on the porous silicon surface morphology. ► FeNi thin films compositions are found to depend on the porous silicon microstructure. ► XRD spectra show the presence of FeNi (111) and FeNi (220) peaks. ► FeNi (111) peak has been shown for all polarization potentials.
