Electrodeposition of Nanometer Sized Nuclei of Cobalt-Nickel Alloys on Silicon Monocrystal

Nanometer-sized nuclei of Co-Ni alloys were electrodeposited on n-Si (100) electrodes from buffered solutions containing metallic ions. It was determined that electrodeposition occurs via a 3D progressive nucleation mechanism. The morphology and magnetic properties of the nuclei were studied by Atomic Force Microscopy and Magnetic Force Microscopy, respectively. The energy levels of the interface Si/(Co(II), Ni(II))aq were determined from Mott-Schottky plots. In the present work, it is shown that the electrochemical deposition of alloys on a semiconducting substrate may be used as an especially advantageous and economical in situ technique for production of nanostructures important in high-technology applications, such as production of integrated magnetic sensors, and magnetic data storage ("hard disc"). Electrochemical behavior of metalurgically obtained Co-Ni alloy was investigated in 1M NaOH solution by cyclic voltammetry and impedance spectroscopy techniques.
