Special Issue Information

Dear Colleagues,

It is well known that thin-film coatings are vastly utilized in various applications, including transparent conductive oxides, photocatalysis, gas sensors, hydrophobic and hydrophilic surfaces, bio-sensors, plasmonic devices, solar cells, MEMS, etc. Therefore, we invite you to contribute to the Special Issue of Coatings, entitled ”Recent Advances in Metallic and Metal oxide Thin Films”, on the different improvements and developments over the past decade in relation to the fabrication of different metallic and metal oxide thin film technologies for different applications. In particular, the topics of interest include, but are not limited to, the following:

  1. metallic coatings over different organic and inorganic surfaces;
  2. improvements in the metal oxide semiconductor depositions techniques;
  3. current and future applications of metallic and metal oxide thin films;
  4. analysis of different structural, morphological, optical, electrical, and chemical properties of thin films;
  5. gas sensing properties of metal and metal oxide thin films;
  6. photocatalytic properties of pure and modified metal oxide coatings;
  7. electrochromic properties of metallic and metla oxide coatings.

Abstract
Nanostructured Zinc Oxide (ZnO) was deposited on silicon (c-Si) and macroporous silicon (m-PS) using a radio frequency (RF) reactive magnetron sputtering technique. Two RF powers of 60 and 80 W were selected for ZnO deposition on the substrates. Furthermore, the c-Si and m-PS [...] Read more.
Nanostructured Zinc Oxide (ZnO) was deposited on silicon (c-Si) and macroporous silicon (m-PS) using a radio frequency (RF) reactive magnetron sputtering technique. Two RF powers of 60 and 80 W were selected for ZnO deposition on the substrates. Furthermore, the c-Si and m-PS substrate temperatures were kept at 500 and 800 °C, respectively. The morphological, structural, and optical characteristics of the samples were studied using scanning electron microscopy (SEM), an X-ray diffractometer (XRD), X-ray photoelectron spectroscopy (XPS), and photoluminescence spectroscopy (PL). The SEM images revealed the formation of ZnO nanorods on the c-Si and ZnO nanostructures constituted by the assembly of nanorods. It has been found that the increasing RF sputtering power caused the rise in the residual stress. In addition, the increase in the deposition temperature caused an improvement in the arrangement of the crystals, which was attributed to the decrease in crystal defects. Full article

Molybdenum oxide (MoO3) electrochromic (EC) materials have not been widely used at present due to relatively poor performance and inadequate research. In order to enhance the EC properties of the MoO3 to achieve the purpose of practical use, the modified nanocrystalline MoO3 films were fabricated by a cheap and simple complexation-assisted sol–gel method followed by annealing at 300 °C. In this method, dopamine (DA) is used as a structure-directing agent and the added amount of DA has a great influence on the structure and morphology and, thus, electrochemical and EC properties of the MoO3 films. Different from the pure MoO3 polycrystalline film, the film modified with a suitable amount of DA possesses a distinctive nanocrystal-embedded amorphous structure, and, thus, can achieve synergy effects of EC properties through combining the advantages of both amorphous phases and nanocrystalline. Therefore, compared with the pure MoO3 film, the modified MoO3 film shows much higher EC properties in terms of optical contrast, coloration efficiency, switching speed, and cycling stability. Moreover, a complementary type EC device with dual active layers (the modified MoO3 film and polyaniline) was fabricated and tested, and the results demonstrate the potential application of the modified MoO3 film.
