Al doped ZnO (AZO) nano-composite films were synthesized on glass substrates with the sol gel spin coating method at the room temperature. The activation energy of AZO nano-composite films was calculated to be 49 kj/mol for the particles growth. The electrical structural and optical properties of AZO films were determined by changing ZnO:water and ZnO:Al ratios. ZnO:water and ZnO:Al ratios play an important role in controlling the electrical conductivity of the AZO nano-composite films. The optimum ...
