Abstract:
1. A method of forming a film on a substrate by electrodeposition comprising: immersing the substrate in an electrolyte comprising a predetermined concentration of ions of a mediating element and a predetermined concentration of ions of a material to be deposited as the film; initiating a reverse potential sweep at a first potential which is less than the bulk deposition potential of the material to be deposited as the film; sweeping the potential applied to the substrate in a negative direction at a first sweep rate; stopping the negative sweep at a second potential which is greater than a bulk deposition potential of the mediating element; sweeping the potential applied to the substrate in a positive direction at a second sweep rate; stopping the positive sweep at the first potential; and repeating the negative and positive sweeps between the first and second potentials.
