Special Issue Information

Dear Colleagues,

Materials, a peer-reviewed open access journal of materials science and engineering, plans to publish a Special Issue titled “The Composition and Photoelectrochemical Performance of Thin Films.” The main aim of this Special Issue is to serve scientists and engineers active in the fields of thin-film synthesis and its diagnostics, surface science, nanostructures (chemical composition, crystal phase) and finally their characterization (including composition and photoelectrochemical performance) and applications.

The scope of the Special Issue includes results of materials science, specific surface analytical techniques, theoretical and computational methods, the processing of films and nanostructures and applied physics, with special emphasis on the following topics:

  • Deposition techniques, growth and characterization of thin films
  • Thin film, surfaces and interfaces
  • Photoactive thin films and energy harvesting
  • Langmuir-Blodgett and Related Films
  • Nanostructured thin films and surfaces, including manipulation of matter at atomic/molecular scale and assembly phenomena (2D assembly)
  • Condensed Matter Film Behaviour
  • Mechanics and nanomechanics of thin films
  • Theoretical calculations/modelling of thin films
  • Electronics, Optics, and Opto-electronics of thin films
  • Surface modification by laser radiation, ion, electron beams and plasma interactions
  • Thin Film Devices, Sensors, and Actuators
  • Surface science of catalysis, electrocatalysis and photocatalysis, chemistry at electrified interfaces
  • Surface nano-engineering and functionalization,
  • Thin films application for energy conversion and storage

The deposition processes may include: pulsed laser deposition, physical and chemical vapour deposition, thermal and plasma spraying, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting. Tribology and bio surfaces are not in the issue’s scope. Special attention should be paid to the material response during its exposure to the whole solar spectrum or the particular wavelengths.

Work published in Materials reaches a wide range of specialists, in fields ranging from chemistry and physics to biology, materials science and engineering. The Special Issue will provide an excellent forum for cross-fertilization of ideas and broad dissemination of presented results. We expect contributions to range from original scientific articles concerned with applied research or direct applications of thin films, as well as reviews of current technology in specific areas (in the latter case please send your proposal beforehand).

Papers should comply with the general journal requirements as described at https://0-www-mdpi-com.brum.beds.ac.uk/journal/materials/instructions

It is my pleasure to invite you to submit a manuscript for this Special Issue of Materials. Fundamental, interdisciplinary, theoretical, experimental and applied work will be considered. You are encouraged to write articles that are of relevance and interest to both established surface scientists and newcomers to the field.

Carbon nitride materials have received much attention due to their excellent tribological, mechanical and optical properties. It was found that these qualities depend on the N/C ratio; therefore, the possibility to control it in situ in the sputtered film is of high importance. The plasma-electron spectroscopy method based on the Penning ionization process analysis is developed here to control this ratio in CNx films produced by plasma-sputtering in a pulsed-periodic regime of glow discharge. The electron energy distribution function is determined by the means of a single Langmuir probe placed in the center of the discharge tube. The mixture N2:CH4:He was used in the process of sputtering. The applied concentrations of CH4 varied in the range of 2–8%, and He concentration was 80–90%. The gas pressure in the discharge tube used for sputtering varied between 1 and 10 Torr, and the current was between 10 and 50 mA. It was shown that the proposed method enables the extraction of information on the composition of the surface layer of the investigated film and the development of an on-line inspection, without extracting the film from the sputtering chamber.

The miniaturization of devices requires the introduction of a high aspect ratio through patterning in the Damascene copper interconnect process. The high aspect ratio etch process employs hardmasks, such as amorphous carbon, that can withstand high-powered plasma exposure. When an etch hardmask is removed after patterning, the properties of the underlying film can be altered by the effect of plasma exposure during the strip process. In this study, surface properties of SiOC(H) are investigated after an amorphous carbon strip with O2/Ar plasma. Since the low-k film of SiOC(H) structure shows characteristics according to the Si-O internal bonding structure, the Si-O bonding ratio of the ring, network and cage structure was analyzed through Fourier-transform infrared (FT-IR) analysis to measure changes in thin film properties. X-ray photoelectron spectroscopy (XPS) was also used to add reliability to the SiOC(H) film structure. In addition, the end point of the strip process was obtained using an optical emission spectroscopy sensor and variations in thin film characteristics over the plasma exposure time were analyzed. These results revealed the structural modification of the SiCO(H) thin film in the post-etch strip of the amorphous carbon layer (ACL) hardmask. Full article
