Fabricated CdO-ZnO Films: A Potential Candidate for Optoelectronics Device Applications

Fabrication of transparent conductive oxides (TCO)-based material has gained much importance because of its exceptional industrial applications. This Chapter reports preparation and characterizations of pure CdO and Zn-doped Cd0.75Zn0.25O screen printing films on glass substrates. For structural characteristics, X-ray diffraction (XRD) shows nature of polycrystalline for pure CdO film, whereas Cd0.75Zn0.25O film shows mixed phase of CdO and ZnO with maximum diffraction at (111) plane. For optical property, UV–visible spectra show optical band gap energies of 2.43 eV for CdO and 2.87 eV for Cd0.75Zn0.25O film followed by direct transition. The DC conduction mechanism from two-probe method confirms the semiconductor nature of the films.
