AC impedance and cyclic voltammetry studies on PbS semiconducting film prepared by electrodeposition

► Deposition of lead sulfide film on SS substrate by cyclic voltammetry technique. ► Study of oxidation and reduction of the PbS film in neutral Na2SO4 solution. ► Investigation of PbS/Na2SO4 interface by impedance spectroscopy. ► Extraction of semiconducting properties of PbS film from Mott-Schottky plot.
