AbstractHighly transparent CuO-doped p-type ZnAl O (AZO; Al/Zn = 1.5 at%) conducting oxide films were synthesized on glass substrates using a cost effective low temperature sol-gel method. X-ray diffraction of the CuO-doped AZO (AZO:CuO) films revealed a polycrystalline CuO (1 1 0) peak. The I-V measurements of the p-n junction (ITO/AZO:CuO) revealed rectifying I-V characteristics, showing that these AZO:CuO films exhibit p-type conductivity. p-Type conductivity was achieved by annealing the AZO:Cu O films in N/H forming gas at 400 °C. The hole concentration, hole mobility and resistivity of the 0.5-2 mol% AZO:CuO films were 5.41 × 10 to 1.99 × 10 cm, 8.36-21.6 cm/V s and 1.66 × 10 to 6.94 × 10 Ω cm, respectively. These results show that post-annealing in a forming gas is effective and practicable in producing p-type AZO. © 2012 Elsevier Ltd.
