Copper thin films are provide through chemical bath deposition method (CBD). Forthis study iron pyrite thin films were prepared by using the chemical bath deposition methodin aqueous solution. Deposition time constant at 60 minutes and pH of the solution at 2.0.Substrate is the surface is used to deposit thin film. The CDS (CU) thin film is deposited onthe glass substrate by using chemical both deposition method at 800c in three hours. With thehelp of XRD analysis CDS (cu) thin film has hexagonal crystalline structure.
