ABSTRACT:
A simple and inexpensive spray pyrolysis technique (SPT) was employed to deposit nickel oxide (NiO) thin films on to glass substrates at 573 K using nickel chloride as starting solution. The optical and electrical properties were studied using optical absorption, electrical resistivity and thermoelectric power (TEP) techniques. The optical characterization shows that the band gap of the spray deposited NiO thin film is 3.3eV.The electrical resistivity of NiO thin film is of the order of 106 Ωcm. The thermo-emf measurement confirms n-type conductivity of NiO thin films.
