Topical Collection Information

Dear Colleagues,

You are invited to submit your work to this Feature Paper Collection on Plasma, which focuses on low-temperature plasma theory and applications. Low-temperature plasmas are widely used for manufacturing semiconductor devices, tribological coatings, displays, solar panels, and many more technical products. On one hand, fully understanding plasma behavior requires the combined effort of simulation and diagnostics. Accurate simulation of plasmas, especially at low pressures (<100 mTorr), is computationally extensive due to the requiements to resolve the fastest temporal process and the finest spatial behavior of electrons. On the other hand, industry production has continuously driven the development of more efficient plasma sources and processes. Some particular challenges include large-area coatings at high frequencies, material-induced restriction to the process temperature, and capability to tune coatings’ microstructures. This feature Paper Collection aims to introduce the latest experimental, computational, and theoretical developments in the field of low-temperature plasma, through a series of original work and review articles from leading researchers around the world.

Potential topics include but are not limited to:

  • Modeling and diagnostic methods of plasma discharges;
  • Fundamental understanding of plasma behavior;
  • Plasma-enhanced coatings and structures;
  • Plasma-surface interactions;
  • Novel plasma-based thin film deposition and material synthesis technology;
  • Implementation of plasma processing for research and industrial applications.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the collection website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Coatings is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Deposition of (Ti-Al)N/MoN multilayered coatings was carried out through a cathodic ion-plating system in an argon and then nitrogen atmosphere. Bilayer thickness (Λ) of all the samples were achieved, from 22 to 104 nm, by organizing substrate holder rotational speed (SRS). To obtain the optimum properties of the (Ti-Al)N/MoN coatings, the Ti and Al ratio was maintained at a level of 1:1. X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy were utilized to analyze the crystal structure and morphology of the coatings. Mechanical and tribological properties were examined by nanohardness and atomic force microscopy (AFM). The preferred orientation of the (Ti-Al)N/MoN nanoscale multilayer films was TiAlN (200) and MoN (200), which had face centered cubic (fcc) and hexagonal structures, respectively. The hardness increased with the decrease in Λ (104 nm to 26 nm), and then it increased. The highest hardness of 37 GPa was revealed at Λ = 26 nm, whereas the least wear rate of 8.09 × 10−7 mm3/N.m was attained at Λ = 22 nm. Wear rate, roughness, and coefficient of friction were decreased with decreasing bilayer period. EDS results showed that Al and Ti contents were almost the same in all samples, as per design of the experiment. Full article
