ZnO films were grown on Si(100) and quartz substrates by inductively coupled plasma assisted chemical vapor deposition (ICP-CVD), using metal organic DEZ (diethlyzinc), and a gas mixture of Ar and O 2 . The process temperature ranged between room temperature and 400 °C. ZnO films showed both p- and n-type electrical properties according to the oxygen flow rates. By using inductively coupled plasma (ICP), promotion of dissociation and activation of oxygen gas was caused and solved the lack of oxygen in the films, which produced the native Zn vacancy. Consequently, the p-type electrical property of ZnO films was realized. From the Hall and resistivity measurements, the p-type ZnO films showed the resistivity in the range of 4.7 × 10 − 3 and 9.7 × 10 − 3  Ω cm. hole mobility and the concentration of the film ranged from 200 to 272 cm 2 /V·s and from 2.4 × 10 18 to 6.6 × 10 18  cm − 3 .

Electrical and optical properties of undoped p-type ZnO films

Thin films of zinc oxide have been deposited onto glass/FTO substrates at optimized 400 °C by using a chemical spray pyrolysis technique. Deposited films are character photocatalytic activity by using XRD, an SEM, a UV-vis spectrophotometer, and a PEC single-cell reactor. Films are polycrystalline and have a hexagonal (wurtzite) crystal structure with c-axis (002) orientation growth perpendicular to the substrate surface. The observed direct band gap is about 3.22 eV for typical films prepared at 400 °C. The photocatalytic activity of starch with a ZnO photocatalyst has been studied by using a novel photoelectrocatalytic process.

Photoelectrocatrocatalytic hydrolysis of starch by using sprayed ZnO thin films

This work presents a novel technique to deposit ZnO thin films through a metal vacuum evaporation technique using colloidal nanoparticles (average size of 30 nm), which were synthesized by our research group, as source. These thin films had a thickness between 45 and 123 nm as measured by profilometry. XRD patterns of the deposited thin films were obtained. According to the HRSEM micrographs worm-shaped nanostructures are observed in samples annealed at 600 °C and this characteristic disappears as the annealing temperature increases. The films obtained were annealed from 25 to 1000 °C, showing a gradual increase in transmittance spectra up to 85%. The optical band gaps obtained for these films are about 3.22 eV. The PL measurement shows an emission in the red and in the violet region and there is a correlation with the annealing process.

Growth of amorphous zinc tin oxide films using plasma-enhanced atomic layer deposition from bis(1-dimethylamino-2-methyl-2propoxy)tin, diethylzinc, and oxygen plasma

We experimentally find that the ZnO thin films deposited by dc-magnetron sputtering have different conduction types after annealing at high temperature in different ambient Hall measurements show that ZnO films annealed at 1100?C in N2 and in O2 ambient become n-type and p-type, respectively This is due to the generation of different intrinsic defects by annealing in different ambient X-ray photoelectron spectroscopy and photolumi-nescence measurements indicate that zinc interstitial becomes a main defects after annealing at 1100?C in N2 ambient, and these defects play an important role for n-type conductivity of ZnO While the ZnO films annealed at 1100?C in O2 ambient, the oxygen antisite contributes ZnO films to p-type
