dc.description.abstract | In this work, the effect of indium (In) and gallium (Ga) dopants on the structural, optical and
electrical properties of ZnO thin films was studied. ZnO thin films were deposited on glass substrates
at 400°C using the spray pyrolysis deposition technique. X-ray diffraction (XRD) results indicated
that both undoped and doped ZnO films had (002) preferred orientation. The undoped ZnO films
were found to exhibit high transmittance above 80%, while indium-doped (In:ZnO) and galliumdoped (Ga:ZnO) films had transmittance above 60% and 70% respectively. From the Hall Effect
measurements, doping improved the conductivity of the ZnO thin films however, In:ZnO films showed
higher electrical conductivity compared to Ga:ZnO films. Electron probe microanalysis (EPMA) results
were used to confirm the presence of the respective dopants in the thin film samples. | en_US |
