Table 1. Chemicals and their concentrations for the three electrolytes used in the electrodeposition of Ni–Co films on Si/Ti/Au substrates. Note that Baths 1 and 2 contained P-123 as a structure-directing agent to produce mesoporous Ni–Co films while Bath 3 did not include P-123, resulting in dense Ni–Co films.
