A single layer composite transparent conducting oxide films (NiO:AZO) was successfully synthesized by a simple and low cost sol-gel solution method. The results indicated that the enhancement of conductivity could be achieved by annealing the NiO:AZO films in N2/H2 forming gas. P-type conductivity of NiO:AZO film with resistivity of 1.24×10-3 Ωcm, p-type carrier concentration of 4.09×1020 cm -3, and a Hall mobility of 12.7 cm2/Vs were obtained when molar ratio of NiO is 1.5%. This study opens the possibility of developing high conductive p-type composite transparent conducting oxide for optoelectronics devices.
