Influence of a Ni buffer layer on the optical and electrical properties of GZO/Ni bi-layered films

Ga-doped ZnO (GZO) and GZO/Ni bi-layered films were prepared on polycarbonate (PC) substrates by DC and RF magnetron sputtering at room temperature in order to determine the influence of a Ni buffer layer on the structural, optical, and electrical properties of the GZO/Ni films. The thickness of the Ni buffer layer was varied between 2 and 5 nm. As-deposited GZO films that contained the PC substrate show an average optical transmittance of 81.3%...
