In order to improve the transparency and durability of the Cu films deposited on polycarbonate (PC) substrates, a Ga-doped ZnO (GZO) layer could be deposited directly onto the Cu film. Compared with a single-layered GZO film, the GZO/Cu multilayer coatings have much lower sheet resistance and much thinner thickness. In our work, GZO/Cu multilayers were deposited by magnetron sputtering on PC substrates at room temperature. The structural, electrical, and optical properties of multilayers were investigated at various thicknesses of the Cu and GZO layers. As the Cu layer thickness increases, the...
