ABSTRACT Nickel oxide (NiO) thin film has been deposited on a glass substrate at a temperature of 390°C ± 10°C using a simple and inexpensive spray pyrolysis technique. Nickel nitrate salt solution (Ni(NO 3 ) 2 · 6H 2 O) was employed to prepare the films and the film thickness was in order of 200 ± 5 nm. The structural, optical and electrical properties of NiO films were investigated using X-ray diffraction (XRD), visible spectrum, DC conductivity and Seebeck effect measu...
