- NiO-AZO thin films were prepared by DC and RF magnetron co-sputtering (MCS) system in an O 2 atmosphere. The lowest resistivity of 1.75 × 10 - 1 廓 cm was obtained in the film containing 1.94 mol% Al. The I-V measurements of the p-n junction ((NiO-AZO)/ITO) revealed rectifying characteristics, demonstrating that the film possess p-type conductivity. These results showed good agreement with the X-ray photoelectron spectroscopy (XPS) data by the higher bond enthalpy of Ni-O (382 짹 16.7 kJ/mol) than Zn-O (159 짹 4 kJ/mol). Moreover, the NiO-AZO films had a higher work function than NiO, highlighting the potential applications of transparent contact electrodes in Gallium nitride LEDs. © 2012 Elsevier B.V.
