Abstract: 

Using the spray pyrolysis technique to prepare the P-type CuO thin films. It is carried out for one molar concentrations of 0.1M at 250°C from copper acetate precursor solution on the glass substrate. The study of X-ray diffraction attained all the films exhibit polycrystalline nature with monoclinic crystal structure comprised uniformly distributed grains. The electrical properties of the films like mobility, conductivity Hall co-efficient (RH), and carrier concentration have been studied. Hall Effect measurement is to confirm the p-type conductivity of the films. The bandgap energy size, resistivity and average particle were also determined. The resistivity has been investigated by four probe method for different molar concentrations of copper oxide.
