Oxygen-free and low resistivity nickel (Ni) thin films are successfully prepared by plasma-assisted atomic layer deposition using nickelocene (NiCp2) as a metal precursor and ammonia (NH3) as a reactant.

Doping Ratio

The AZO transparent conductive films are prepared by the atomic layer deposition (ALD) at a low temperature of 150 °C. The different Al–Zn doping ratios were designed during the deposition. The phase structure of the films was characterized by XRD, the electrical properties of thin films were analyzed by the Holzer test, and the optical properties of thin films were analyzed by the UV-3600 (UV-VIS-NIR) spectrophotometer. The results showed that all the films preferred the orientation of the C axis during the growth process, the AZO films have a very low resistivity of 6.955×10−4 Ω·cm with the Al doping ratio by 2%, the deposition temperature is 150 °C and the thickness of the film is 200 nm. The transmission of AZO films with the different doping ratios in the visible region is 85%. The proper doping ratio can be selected to get the excellent photoelectric properties of AZO thin films. Such low resistivity AZO transparent conductive film is expected to replace the ITO as the transparent electrode for the organic light-emitting devices and the other new generation of the optoelectronic devices.

The post-annealing effects on the surface morphological changes of undoped and Al-doped ZnO (ZnO:Al) thin films deposited by atomic layer deposition (ALD) were investigated. The as-grown films were deposited by ALD at growth temperature of 200°C and also, post-annealing of the samples was accomplished at 300°C for 1 h under nitrogen atmosphere. The X-ray diffraction of the films was monitored to study the crystallinity of the films according to post-anneal. The field emission-scanning electron microscopy and atomic force microscopy were conducted to observe the surface morphological changes and measure the root-mean-square roughness of the films in order to analysis the post-annealing effects on the surface roughness of the films.

Thin films of the catalytically interesting ternary and quaternary perovskites GdCoO3 and Gd0.9Ca0.1CoO3 are fabricated by atomic layer deposition using metal β-diketonates and ozone as precursors. The resulting thin films are amorphous as deposited and become single-oriented crystalline on LaAlO3(100) and YAlO3(100/010) after post-annealing at 650 °C in air. The crystal orientations of the films are tunable by choice and the orientation of the substrate, mitigated through the interface via solid face epitaxy upon annealing. The films exhibit no sign of Co2+. Additionally, high-aspect-ratio Si(100) substrates were used to document the suitability of the developed process for the preparation of coatings on more complex, high-surface-area structures. We believe that coatings of GdCoO3 and Gd1−xCaxCoO3 may find applications within oxidation catalysis.
