Structural and optical properties of Cu 2O crystalline electrodeposited films

O band gap with Cu–Cu interactions [18]. Theattenuation of Cu–Cu interactions leads to an enhancement of the bandgap.The growth of a preferential crystall ographic direction in a depositionprocess can be regulated by the matching between the growing layer tothe substrate at the interface or by speci ficenvironmentalconditionsonthe growing surface of the substrate during the grown. In this work, wewill show that for the electrodeposition of Cu
