  The Fe-doped CuO thin films were deposited onto glass substrates by Spray
pyrolysis technique. The structural, micro-structural, optical and electrical
properties of the synthesized samples were investigated in details. The X-Ray
diffraction (XRD), Raman and Fourier Transform Infrared (FTIR) spectroscopy,
confirmed that the studied samples exhibit single phase monoclinic structure of
CuO. The UV-VIS spectrophotometer mentioned that the transmittance increases to
80 % when increasing the Fe concentration. Furthermore, the band gap energy of
the obtained CuO was 1.29 eV. This value was slightly increased by the Fe
substitution. In addition, the electrical properties of the films such as the
conductivity, the mobility, the resistivity and the carrier concentration have
been studied. The Hall Effect measurements confirmed the p-type conductivity of
the studied films.
