ZnOTe Compounds Grown by DC-Magnetron Co-Sputtering

ZnOTe compounds were grown by DC magnetron cosputtering from pure Tellurium (Te) and Zinc (Zn) cathodes in O2/Ar atmosphere. The applied power on the Zn target was constant equal to 100 W, while one Te took two values, i.e., 5 W 10 W. Thus, sample series obtained which variable parameter distance targets substrate. Sample compositions determined Rutherford Backscattering Spectroscopy (RBS) experiments. Structural analysis done using X-Ray diffraction (XRD) spectrometry growth of hexagonal w-ZnO phase identified XRD spectra. RBS results showed high bulk homogeneity samples forming alloys, with molar fraction (MF) ranging 0.48–0.6% 1.9–3.1% for at respectively. reflect great differences between series, particularly structural optical point view. These experiments possibility doping ZnO permanence intrinsic defects, as well formation other solid phases when its content increases. appreciable variations band gap transitions detected Photoluminescence (PL) measurements.
