Deposited Films

ZnO thin films were deposited on quartz substrates by RF sputtering under argon, oxygen and nitrogen gas environment. The as deposited films showed hexagonal wurtzite structure with (002) orientation along c-axis. The mechanical properties of films with thickness ranging from 842[Formula: see text]nm to 1067[Formula: see text]nm and grain size 94–124[Formula: see text]nm were studied using nanoindentation technique. The Young’s modulus and hardness of the films were in the range 76–257[Formula: see text]GPa and 5–18[Formula: see text]GPa, respectively. Both parameters decreased with increase in indentation depth of the films. The spatial distribution of these parameters were strongly dependent on the gas environment used for film deposition.

Undoped and transition metals (TM = Cr, Ni, Mn and Cd) doped zinc oxide (ZnO) thin films were prepared by sol-gel dip-coating method on glass substrates at 300 °C. In this study, the effect of dopant material on the structural, morphological, optical, electrical and mechanical properties of ZnO thin films is investigated by using XRD, AFM, UV-Vis, Hall effect and nanoindentation techniques, respectively. Nanocrystalline films with a ZnO hexagonal wurtzite structure and two preferred orientations (002) and (103) were obtained. UV-Vis transmittance spectra showed that all the films are highly transparent in the visible region (> 80 %). Moreover, the optical band gap of the films decreased to 3.13 eV with an increasing orbital occupation number of 3d electrons. AFM-topography shows that the films are dense, smooth and uniform, except for the high roughness RMS =26.3 nm obtained for Cd-doped ZnO. Finally, the dopant material is found to have a significant effect on the mechanical behavior of ZnO as compared to the undoped material. For Ni and Cd dopants, analysis of load and unload data yields an increase in the hardness (8.96 ± 0.22 GPa) and Young’s modulus (122 ± 7.46 GPa) of ZnO as compared to Cr and Mn dopants. Therefore, Ni and Cd are the appropriate dopants for the design and application of ZnO-based nanoelectromechanical systems.

In the present work the mechanical properties of ZnO thin films, deposited on Si (100) substrates, were studied using the nanoindentation technique. ZnO thin films were deposited by radiofrequency sputtering from a ZnO target with different H2/Ar gas mixtures. During the deposition the plasma species were in-situ monitored using optical emission spectroscopy (OES). The results showed that the introduction of H2 in the plasma phase had a strong effect on the material’s hardness and elastic modulus. The measured elastic modulus values were then related to the material density to estimate the porosity of the ZnO films. We found an increased film porosity when H2 was added to the sputtering gas, from 6% to 18% in volume. Moreover we found that the porosity was correlated by the emission intensity ratio of atomic Argon on atomic Hydrogen.
