Abstract

Cu-S nanocabbage films were synthesized on ITO substrate using pulse electrodeposition at elevated temperatures in aqueous solution. The bandgap of the films showed a dependence on reaction time and was found to increase linearly with reaction time. This increase was attributed to the change in phase and stoichiometry of the Cu-S nanocabbage films. The stability of Cu-S films is found to be improved substantially when deposited at higher temperature because the Cu atoms have sufficient energy to find the minimum energy site in the lattice.
