Electrodeposition Of Mn-bi Rosalike Thin Films

Abstract

This work focuses on the electrodeposition of the Mn-Bi system from a mixed sulfate-nitrate bath on a polycrystalline Cu substrate. The electrochemical analyses are carried out by cyclic voltammetry. The effect of some experimental conditions on the deposit morphology and composition are investigated with a scanning electron microscopy (SEM-FEG) and the energy dispersive spectroscopy (EDS) respectively. The Mn-Bi deposits have a rosalike-shaped appearance with a heterogeneous distribution of manganese and bismuth. The EDS analysis shows that the Mn and Bi content in the deposit depend strongly on the pH bath and the applied potential.
